transition from trial version to paid version

[Ingrid64]

I made a video in the trial version of adobe premiere elements 2020. This starts with a title with movement. Now I bought adobe and transferred the movie to the new version. However, the black bar of the trial version remains in the title, the bar disappears further in the video. Does anyone know how to get that black bar out?
