Trying to set pictureType for all files

I am trying to use the cli to set all Picture frames to be pictureType 3 (front cover). All of the files only have 1 Picture frame, and only have a Tag 2, no Tag 1.

I ran the below series of commands and it worked for some of the files but didn’t change all of them.

kid3-cli -c “timeout off” -c “filter ‘%{picture.pictureType} equals 0’” -c “select all” -c “set picture.pictureType 3”

I’m able to update the pictureType of the remaining files individually, but when I select more than one file at a time with the cli, they don’t change. With the GUI I’m able to change an album worth of files at a time but I’d rather not have to do that for everything.

Is the problem also present if you do not use the filter command?
