I just saved a scribe called "Test Scribe".
Notice the 3rd image is a morph of the 2nd.
During playback BOTH the 2nd and the 3rd image disappear. (i.e. the 3rd does not remain on the screen like it should).
I noticed you had a different issue with this scribe and I have responded to your other question.
I have slightly adjusted the size of the third elements and it now appears.
Are these custom SVG's you are using in this scribe?
If so, are you able to advise how they were made? What tools you used and what save settings you used?
