Door Panels Reverting to Simplified Model View

[ETSaum]

I opened up a Teamwork project, and almost all of the doors (Door object) had reverted in both 2D and 3D to the simplest possible view. They are all set to Full detail, yet they won't show that way. A new 'Detail Level' option under Door Selection Settings appears, insisting that the @D Detail Level and 3D Detail Level are 'As In Model View Options'. They're not. All of the Model View Options are set to Full.

If I open up a backup PLN or autosaved version of the Teamwork file from several days ago, all of the objects appear normal. So I recreated the Teamwork file... and then, 24 hours later, most of the Doors in *that* Teamwork file went to 2D basic linework / flush panels as well. To be clear, they all still show detailed Door Leaf selections in Door Selection Settings.

The odd thing is that, in 3D view, some of the doors still show full detail, but are the basic linework in 2D.

If I copy and paste walls / doors from other projects, they come in with full detail. But if I copy and paste walls / doors from previous files of this same project, which show the items correctly, they revert to the simplified linework.

Again, all of the Model View Options show Full detail for both 2D and 3D, yet a) most of the doors (some are Door object, some are Pocket Door object, one is Sliding Folding Multipanel Folding) are now simplified 2D linework, b) a few of those doors still show the proper 3D panel configuration, c) doors inserted from previous versions of this project (where they show in Full detail) revert to 2D when inserted, d) doors inserted from other projects insert in Full detail in both 2D and 3D, and e) when I created a Teamwork file from an old PLN that still showed Full detail, it reverted to the 2D setting a day later.

Enormously frustrating...

It's clearly something in the file itself, because, if I cut and paste a wall / door that is incorrectly showing simplified linework into another project (or old PLN from the same project), it shows in proper Full detail.
