Collection list keeps shifting files while building playlist

i have my itunes library that i import into engine.

i just updated itunes today and then refreshed in engine. all new files have been imported/analyzed.

i open the collection view on the local library and sort by Date Added.

as i’m playing through the list of new songs and adding to a playlist, each song i open disappears from the list after i open the next song, and it’s moved (i guess) further down the list. i don’t know what’s happening but the list should not have to update when you drag a song into a playlist. does Date Added get updated every time you open a song in ep?
