Cut/Insert Time still shifting markers & MIDI clips in PT 2021.6

[take77]

Hello,

I would just like to insert & cut a couple sections in my session (PT 2021.6|W10).
When selecting the bar length I've made sure to select the "realign all markers" option in the cut/insert dialogue.

The result is that most all of the markers & MIDI clips following the cuts/inserts are now shifted out of line with the start of each measure.
I can tell it happens when the yellow line looks slightly blurry because of the small gap between the bar grid line and the marker line.
Zooming in and see the markers & MIDI notes have indeed shifted .
I'll create a screenshot when I have time to open a ticket.

I made the session all one tempo to see if this would help.
Current tempo is 120BPM @44.1kHz
Have tried both samples & tick options in the top left corner. Normally, no issues in global sample mode with individual instrument tracks in tick mode.

Can any one please be kind enough to take the time to try and repro the issue?

Thanks

Man it's a bummer that I've spent hours readjusting marker locations as well as hundreds of MIDI notes after one simple time cut and now I can't reproduce the marker shifts in a new session.
I guess there has to be MIDI notes on the timeline to reproduce the problem and that it's the MIDI/sample rounding issue that's causing the marker shifts.

I'll try & repro with some basic drum loop sections.

Update: Well I guess the session I've been working on is the issue. Because I can do everything I was trying to do in a new session without any problems so far. I'm happy about that and frustrated at the same time.
One simple time cut cost me extra hours of work readjusting all the shifts made to all the instrument tracks.
I did import the session data from a previous session that contained both audio & MIDI so maybe a sample based glitch carried over somehow.

I'm also thinking it might take multiple MIDI tracks to reproduce the problem.
