Pro Tools 12 - 2019.6.0 Memory Location Problem

I create memory locations in order to recall seeing certain tracks and track heights at certain times for editing; in this case, all of the tracks, the piano tracks, and acoustic guitar tracks.
However, when I close Pro Tools and open it back up, when I try to recall these memory locations, they are completely wrong and all over the place. I have replicated this problem three times and it still continues.
Wondering if anyone else has this issue. I'm on Pro Tools 12 version 2019.6.0. Any help is appreciated.

I think I may have solved the issue; there were some tracks, specifically the piano tracks that were still in "Playlist" mode even though the playlists were not displayed and only the waveforms were showing. I deleted the memory locations, made sure all tracks were actually in waveform mode, and then created the memory locations again. They appear to now stay in-tact when opening and closing Pro Tools. Interesting..

I myself don’t understand why this is so...(((
