When using e.g. a color correction filter on any source and changing any value (with slider enabled, e.g. contrast) to -0.10 the value would get cycle between -0.07/-0.08 at some point when using the up arrow; it would also get stuck on -0.69. For the other direction, when starting from e.g. -0.02 the value would jump from 0.05 to -0.08 when pressing the down arrow. Problem was reported at https://obsproject.com/forum/threads/32450
