Perhaps you toggled the “mask” icon, that will tell the control something has changed, and make it bold. If you “Reset to Default” that should reset everything correctly.
We could probably tweak things so this doesn’t happen, but it’s probably not a big deal…
I would have thought that the Spacing heading should still be in blue if any of the controls are overridden (in bold) and it isn’t. That seems like a bug. If the group was collapsed you would have no indication that a control was altered.
As a suggestion, it might be nice to have a function: Collapse all non-modified groups / Expand all modified groups (if all groups collapsed). That would really allow you to focus on what had changed. 
On a right click…. Expand all / collapse all
Okay, new build of 1.6.1 (23985) is up, please check for updates!
I can’t reproduce that issue here. Seems to work as expected. Can you create this issue on a new project with the built-in components?
I’m not sure how useful that would actually be in practice. I’ve certainly not found myself wanting it. We’ll add it to the list for maybe someday.
Thank you - I’m sorted !!
This was the best improvement of the month. Much appreciated.
Great job. However, I’d like to express some concern regarding the new ‘visual highlighting for inspector groups.’ While it is a good idea in some respects, turning the text blue whenever a single property is modified feels a bit overkill. Since properties are tweaked very frequently across various groups, there is a real risk that we’ll end up with all the group names in blue (which doesn’t look great, visually speaking). Because ultimately, if they end up being practically all blue, they won’t stand out anymore, and that defeats the whole purpose.
Well for me it is an very helpfull tool. ( i have a bad sight ) Now i dont need too recheck everything. 
Agree, it is already driving me around the bend option to turn it off would be good, same as you can turn outlines etc
I actually like it a lot.. helps me (older eyes) lol 
ok if you make a change it highlights you have made a change but you set back to defaults it still shows you made a change, still at default ??
From your initial post
We now highlight property groups and individual controls whenever they differ from their default values.
this time
I saved and reopened the file, the highlighting was not there before saving save and open remembered the change even though set to default and before saving was not showing the change
ok not sure about this bit
Thanks @upssjw, we know what the issue is and will get it fixed up!
@tpbradley Tom thanks, further testing suggests interaction rather than changing a default and it’s not across the board, able to switch off and on like outlines would be brilliant, I don’t need to know what I changed (already know), once there all blue? What do I need to change to fix an issue, just my thought.
Turning on outlines is the main thing I use, additional info from that would help even more to understand a layout issue. Think the outlines option is probably the most powerful feature, seeing the layout symmetrical etc. smaller screens becomes a bit more difficult, I’m rambling
Not the end of the world having every setting change blue
always this way to inspect
We’ve just shipped a build with a new option, just for you: Elements 1.6.2 (23988)
@dan I already checked out nice
