an internal error has occured ?:0: attempt to compare nil with string

[#1]

Hi

I have just updated to version 10 and it automatically updated my catalogue. When I try and move an image into a different collection I get the following message and it won't move

an internal error has occured ?:0: attempt to compare nil with string

How can I rectify this?

Thanks

Brilliant thanks for that, I changed the sort order in the collection as suggested in this link and it worked 🙂 Thank you!
