Inside Casing Display Issue

[kylevfa]

I'm trying to model an interior casing for my windows however for some reason the casing at the bottom is locked to be 2 1/2" wide. If I decrease or increase my casing dimensions all the other sides change except for the bottom. I went through all my window settings and I could not find a single dimension set to 2 1/2" so I'm not sure where this is coming from. Am I doing something wrong? This is on Archicad 26 Build 5003 USA Full (Apple Silicon).

EDIT - Just tried this in Archicad 27 and it seems to be working fine. Is this an Archicad 26 glitch?

Graphisoft support was directly contacted regarding this issue. The Specialist Duncan Gilchrist was very helpful in getting this resolved and has informed me that within Archicad 26 the bottom casing attributes are handled by using the Apron option in the window settings. If no Apron is on or modified, the default 2 1/2" bottom casing will be seen.
