Mini2, Cura Luzbot Edition, preheat option MIA

What the title says. As of midday today, I don’t seem to be able to preheat the hot end. I can enter temperature into the little window, but where I am used to seeing a button saying “preheat”, I just have “cancel”. Printer heats up the hot end fine for printing, and I have controls for preheating the print bed, but not the hot end. Needless to say, this makes filament changeover nearly impossible…as soon as the hot end cools down much, the extrude/retract buttons grey out, which makes sense.

Running 4.13.10 Cura. Mini 2 firmware 2.1.3.0.27. Help?
