Please fix. mimolive 5.8 - play once & freeze - need fixing

I have a Project Coming up and alot of my sources are in the “Mode” “Play Once & Freeze” this is a great feature however it doesnt work as intended.

Any source that is brought into the layer stack in that mode works well while “Live” until you select another layer in the layer stack then select the previous layer with the “play Once & Freeze” Mode on. The picture disappears from the program window and it stays invisible until you take the layer off then put it back on “LIVE”

Please Have a look.
