Changed made in sculpt mode not saving?

I made a babboon model, and then switched to sculpt mode to add some finer details.
when i switch bad into edit or object model all the details in sculpt mode go away and i’m back to the very basic model.
i’m sure there’s an easy fix for this, i’m super new at this stuff.
can someone help?

Are you using a Multiresolution modifier for sculpting. Have you changed the Preview modifier setting for the level to use for the viewport display ?

thanks so much! that turned out to be the issue.
you’re the best c:
