Can't Process Cuts and Engraving

After updating to 3.15.1, Luban no longer allows me to process cuts and engravings in the same file - it seems like I’m only able to process one object in a file now. I used to be able to create G-Code that cuts and also engraves in the same session, giving the laser two different settings per object in my file. Now, Luban is only showing me one of the two objects I have processed. The text in my objects also show, but then aren’t processed - they don’t show up in the process preview.
