Level filter parameters
When I put the level filter on the clip in the timeline it is set on the RED channel instead of the LUMA channel but it actually operates on the LUMA. If I switch it to the LUMA channel it works on the RED channel. At this point, if I reset the filter by staying on the LUMA channel the filter begins to works again as it is supposed to. If I select the BLUE or the GREEN channel even if I reset the filter it only works on the LUMA or RED channel. The 2 channels are switched after you click on the reset button based on the last selected color channel.
