I encountered a weird bug when messing around with transitions.
When trying to adjust the Temperature Tolerance slider when making a graduated transition, the value will jump to 40 and cannot be changed. Hitting the reset to default button or resetting any of the other sliders will also cause the temp tolerance to jump to 40.
The slider works fine when making a hard cut or changing the active settings.
Edit: The slider doesn't jump to 40 when making a hard cut transition, but the maximum changes from 20 to 40.
