Rapidweaver was updated for Big Sur but no stacks load up!

After updating Rapidweaver to be Big Sur compatible now none of my stacks are showing up! I can see all of them in the folders but they aren’t showing up in the RapidWeaver app! I need to solved this guys. any idea will be great I’m beginning to think Big Sur change the hierarchy of the preferences folder… I’m lost

Update Note:
I change the Addons Location to: Managed by Rapidweaver and everything was back to normal. Good for a quick solution but please tell me how can I have the admins folder on an external drive again without problems. I never let all those files internally, that way I can switch computers and always have what I need.
