While editing filename, LRC tries to delete file

Hi, using LRC 13.1 on a mac pro OS 12.7.3 - 

I frequently edit filenames in the metadata pane of LRC. Often I am removing extra characters from the end of the filename. I click on the filename to make it editable, and click again to position the cursor where I want to edit the filename. I hit the delete key to delete characters in the filename - but if I hit "delete" more than once, LRC sometimes switches to a dialogue window asking me if I want to delete the file. It seems like hitting the "delete" key more than once triggers a "delete file" command. I don't want to delete the file! Of course, this behaviour does not happen every time I try to edit a filename, only occasionally. But it happens often enough that I notice it and it alarms me to look up and see that I'm a click away from deleting a file that I meant to change the filename of.

If this is a bug of some kind, there it is. If this could be some kind of user error, please let me know.

Thanks

Jas
