I've noticed this behavior recently and I think it is relatively new.
When I use [Recall From] to pull in information that includes FX, the channel being used for reference is also manipulated. I don't remember this behavior previously.
In the attached video, a Cue is running with (4) tubes (Ch #5,6,7,8) using an interleaved 917 FX on their pixels. Asking a 5th tube (Ch#1) to "Recall From" causes the referenced tube (Ch#5) to change its behavior. Channel #5 Cells are now showing Manual Selection.
Thanks for taking a look.
