Cant Shift Elevation Heights without thing being deleted

[Anonymous]

I am having problems with my Revit 2019 project.

Every time I try to shift up or down any of my elevations markers, it issues me a Warning: Elements will be deleted. And then all my items selected to that level are instantly deleted.

All I am doing is shifting the level up 1', I don't have any elevation heights locked with dimensions, either.

Is there a way to fix this? 

I did upgrade the file from 2016 to 2019, could this have corrupted my file, by just upgrading?

Hi @Anonymous,

I´d be happy to take a look at your case.

To be able to help you better, I´d like to ask you to do the following: 

1. Upload a simple project file which reproduces the issue and share it through the forum (if you don´t want to share it with the rest of the community, just feel free to send me an A360 Drive- or WeTransfer download link to it in a private message)
2. Record your steps to reproduce the issue using Autodesk Screencast Recorder and using the sharing option "Anyone" and add it to your post, to make sure that I can reproduce the issue

I look forward to hearing from you. 

Best regards,

Hi @Anonymous,

I haven´t heard back from you for a while - do you still need help with this case?
