RapidWeaver Classic: LinkListThing Within BigFooter - Link Edits Revert

I’m running into an odd issue in RapidWeaver Classic using the BigFooter stack along with LinkListThing.

When I edit an item inside LinkListThing and change the URL via the GUI, the change does not persist. Specifically, if I link to an internal page or use an indirect/relative URL, it appears to accept the edit initially, but when I return to the element the URL has reverted or disappeared.

Has anyone encountered this behavior before, or is there a known workaround? I’m trying to determine whether this is a stack-specific issue, a RapidWeaver Classic quirk, or something related to internal linking.

Any insight would be greatly appreciated.
