Problem with re-specifying periodic BCs on re-drawn model (Bug workaround?)

Hello,
When I modify my model by redrawing the geometry, with the result having fewer total vertices than the previous version, I run into a problem when re-specifying the periodic boundary conditions.
In particular, the periodic BC dialog box remembers the vertex numbers from the first version of the geometry. When some of these retained vertices have number-labels larger than the new total number of vertices, I get an error:
Error: 9040
Fatal error.
- Type: ArrayIndexOutOfBoundsException
The catch-22 is that it wont let me remove the out-of-bounds vertex numbers because there are too many of them for the Javascript routine to work with.
Any pointers on how to avoid this? My sub-domain and other settings are rather elaborate, and I would really not have to re-jigger them every time I tweak the geometry. (For context, I am solving Schroedinger's equation on 3D in semiconductor nanostructures that are periodic in 2D, finding the Bloch states.)

Hello
Those kind of behaviour are typically the problems I document more and send as example to COMSOL Support. I havn't notice your particular one, but I have had a few "bugs", but really not many for the complexity of this software.
COMSOL support people have alwas given me rapid replies, and / or work-arounds
As a general remark, send your model(s) with sequence explanations what you are doing, use screen Snipping" to explain
Good luck
