AFAIK a proper multi toolhead support (incl. Prusa XL) is not available in 2.1.1 (see #6087)
Would you try using the latest nightly and see if the issue persists?

my wrong on version number. I was using the latest dev, so the bug is still there. See the discord

confirmed with the latest dev:

Probably a firmware bug. Sunday evening I will test it (prusaslicer, with default stealth on, adds a Q param to m104.1)

as explained here #6345, M104.1 is useless because it is processed as it was standard M104 by prusa fw...

M104.1 should be disabled, at least for current tool
