Annotations coming back like a Zombie


I imported a file from my i-pad folder.

There is zero annotation on it.

Its a completely new file.

And then I add it to my study.

Suddenly in the study I see that there are annotations I made and deleted a long time ago.

Its seems that only because this file looks similar to the file that was deleted a long time ago, the annotations from somewhere comes back alive…

I don’t even know where the file is.

Can anyone fix this problem?
