Roto shapes disappear before

Hey! I’m new to Silhouette and I’m trying to find way through it… I received some files with some rotos but they messed up on the starting frame of the roto and I’m trying to fill in the missing frames but my rotos only appear on the frame 5 for example and on frame 4 they just disappear… Any idea how can I keep them for the others frames? Thanks in advance

It sounds like the shapes have either 1) keyframes that animate their position where they jump off the screen from one frame to the next or 2) keyframes to animate the opacity from 100 to 0 from one frame to the next. Select the shape and take a look in the Timeline for keyframes at frame 4 and 5. Delete the keyframe of frame 4.
