Loading other position of same file (Shift+P) in dataprep bug

[Beno71]

Description:

I think that when you cancel "Load other position (Shift+P)" in dataprep, it causes an error when you later try to use this functionality again.

Way to reproduce:

Multiple positions of timelapse data, open dataprep, open other position from there, cancel, try to open other position from there again. Nothing happens but you get this non-critical error in the terminal

(Optional) Link to data to reproduce error:
