Warp Markers not Saving

Everytime I use warp markers to line up audio files, I find that if I go back into the song the markers have gone and everything is out of sync. What determines that the warped audio will remain as I’ve left it. The Save option doesn’t seem to be the answer. I’m having to record the idea as soon as I edit then import back as an audio track. Pulling my hair out on this one…

That’s not the way it should work and indeed it doesn’t for me. Warping and all other sorts of edits are present whenever I open a Cubase project at a later point. Everything else would be disastrous and defeat the purpose of a DAW all together.

Does it happen every time on each event?

Could it be related to “shared copies” vs “real copies”:
