Okay, I found a workaround by chaning it's TextToValueConverter to undefined and setting it there then changing it back to decibels.

core.gain, I can only remove gain -100.0 dB rather than adding like idk +24.0 dB. Is this intentional?

Everytime I try and set the MaxValue to anything higher that 0.0 it just wont, I just started yesterday so I'm quite ignorant to how things work. But it doesn't seem that intuitive to not be able to add gain
