BUG - Shadow/Highlight effect with "Effect Opacity" of "0%" breaks time remapping
In AFX 2021, when using the "Shadow/Highlight" effect on a layer that uses time remapping, setting the "Effect Opacity" (in Compositing Options) to a value of "0" will cause the time remapping to break. When the value is set to "0", the frame of the video displayed when the value is changed will be the freeze-frame. Purging image cache memory can change which frame is displayed, until a value of "0" is set again, then the current frame will freeze again. Similar issue when using keyframes on the "Effect Opacity" with a "0" value. Bug. Needs fixing.
