Complex profile beam cut fill showing weird in AC26

[Algimantas Kuprenas]

Complex profile beam cut fill showing different in same section view in AC26 build 4019 INT. In AC25 it was showing same for all beams. Beam attributes and settings area same. Beams are in contact with roof(insulation) element. 

Does anyone else experience such bug/issue ?

SECTION VIEW. Green - correct, Orange - wrong

It isn't something strange like some of the beams have switched renovation status?

All elements belongs to Existing renovation status.

I'm seeing this in both Archicad 26 and 27. Lazlo N. (community admin) mentioned that for roof and beam elements to cut properly they must be connect + merged with the roof element.  See this post: https://community.graphisoft.com/t5/Modeling/Complex-profile-beam-cut-fill-showing-weird-in-AC26/m-p... .  I see this as a bug, but it could be something on my end.
