Hmmmm, I think I know why.
It’s either you did not upload the overlay to the catalog, or because you mixed up the coding for multiple overlays.
Most overlays are in this similar format (this is my personal way of doing the overlay coding, since it is easier and less messy to deal with, but you can use any way you like!):
@overlay OVERLAYNAME create
@overlay OVERLAYNAME shifts to x y in zone 1
@overlay OVERLAYNAME scales to x y in 0
@overlay OVERLAYNAME moves to layer 0
@overlay OVERLAYNAME opacity x in y
You mixed up multiple overlays when you did the “shifts, scales, moves to layer _” coding, which I’m not sure if it will work regardless if it is separate from the “create” command.
However, as mentioned above, refreshing and fixing up the coding works. ^^
