Variable output from pedalboard + amp DI into interface

Hi guys, I'm having a rather confusing problem with my pedalboard and amp setup. Basically whenever I fire up my rig to jam with headphones it seems that the volume wants to change seemingly randomly even though I leave all the settings the same.

Two days ago I set it for -6 and left it, yesterday I fired it up with those same settings and it was at -3, today -11 for some reason? I'm mainly just confused as I really am not tweaking any settings on the physical units or in my DAW. This isn't the end of the world because I can simply turn up or down on the interface or units but it is annoying and makes zero sense to me why this is happening. If anyone has any ideas what could be causing this or a similar experience please share.
