Ok, I was thinking it was the other way around. That makes total sense though.So it is working perfectly then, boy do I feel stupid. Thanks for the information.

The question wasn't stupid at all. Actually it would be better if 'Preheat ABS Bed' could be 'Preheat ABS Bed Only' but there is not enough space on the display. There is even a bigger problem with the number of digits in other languages than English (Marlin comes in 13 languages up to now).
But there is another issue related to the 'Preheat PLA/ABS Bed' options. When you select a preheat option including a hotend and select the bed only option afterwards, the hotend is still on. I think, it should then switch off the hotend. What do you (or others!) think?
I totally agree. When the ABS Bed choice is made it should completely turn off the hot-end. It makes sense that the ABS 1 choice does not turn off the bed since you want the bed hot before the hot-end.

That's exactly what the fw is supposed to do. The option 'preheat ABS Bed' means to preheat the bed only without preheating any hotend.
Its background is the fact that some heated beds take quite some time to reach target temperature. The hotend might be leaking all the time and at the time the bed is finally heated up, the hotend is empty enough to cause serious underextrusion. Or even worse, the filament is very sensitive and is burned to a brownish slack during the heat-up time of the bed and might cause a clog.
