In the architectural sections the floor of rooms doesn't appear sometimes in complex models.
- the "Floors only on the slab below" option is checked, and there is a contacting slab below the room.
- the minimum thickness of floors is 0, so every floor could to be appear theoretically.

It is an "I don't know, when it happens"-type error. I am not able to reproduce it: sometimes it happens, sometime everything is OK, but in the version 2022-1-7 it was not yet.
Drawing a new slab solve the problem sometimes. Drawing a new room too. Moving the section line with a few mm could be solver also ... but I din't find any universal method to live with this problems day-to-day.
2022-1-8 version was the first wrong version and this error can be experienced since that version (and in all the version 2023-... also).

Is there anybody out there who meet this problem? Could you solve it?
