impossible to move the analytical surface.

[jarjarfix]

Good morning, everyone.
yesterday I installed revit 2023. I opened the work that I had in progress and trying to change the share of a level appears to me the error "impossible to move the analytical surface". I can't pull the way to continue. Can anyone help me?
if the same file (I was predicted and I made a copy) I open it in revit 2022 I can change the level to my liking without problems.
thanks in advance

I solved.... I used the function "show hidden elements", I selected the structural panels (I have no idea what they are) and I deleted them....now I can change the height without problems

I have selected the structural panels (I have no idea what they are)

revit 2023 introduced new objects for the analytic model. I believe they are the old analytical floors converted into the new system
