Moving html files into subfolders shows incorrect paths in navbar options URL

New user here coming over from Mobirise and I'm really liking the concept of Bootstrap Studio.

However I may have found what seems to be a bug. My first project was to create a web site that has about 100 html pages. In an effort to organize the html pages into sections I moved them into subfolders under Pages in the Design section. But when I do this I cannot edit the navbar to link to any of the html files in a subfolder because Bootstrap Studio shows the wrong path to the html files.

However all I have to do is to save the design project, close it, and then reopen it and the correct paths are shown so I can add those pages to links in my navbar.

I search the forum for a similar issue but didn't see anything that sounds like this so I thought I'd file a new bug report.
