Luban and the missing footprint

Anyone else missing the back of the buildplate after the 4.12.0 update?
I know the right side changes depending on what nozzle/settings you choose (brim will decrease the printable area; “none” will expand it). But, since the update now the back of the buildplate shows as unprintable… why!!!
Luban 4.12.0 Ubuntu 22.04.4 LTS.

I figured it out… it now defaults to thinking you have a 2.0 dual extruder. if you go into machine settings and select the correct Artisan dual extruder you get the entire buildplate back (confirmed on Linux and Mac)
