Unwanted drawings in Library restoring upon file re-open

Hi there,

I’ve been having a peculiar issue with the drawing library in Harmony. When I delete extra drawings from the library (not just from the timeline, but using drawings>delete selected drawings) they disappear from the library as I had intended. However, upon re-opening the file at a later date all of the previously deleted drawings in the library have been restored. This issue only happens with drawings that have been imported from another file and are still connected to another scene’s palette. Whenever the drawings colours have been switched out with the current scene’s palette this issue doesn’t occur. Does anyone know what is happening?
