Weird Volume Adjustment Glitch

Super weird glitch in logic where if I select more than one track in the mixer and enter a volume in, some faders don't increase by the same value as the one I'm typing into. If I slide the fader knob they all change equally though. No there's no automation. What makes it even stranger is that if I select ALL tracks in the mixer and enter a volume in on one track, the others change by the same value.

Here's a video example

You'll see at the beginning when I slide the fader knob it behaves correctly. But when I go back and enter the volume in numerically it glitches
