Broken Attachment Group only refreshes once

I am using EndNote X9 on Windows 10. I know that I have several references with broken links to attachments and can find them using EndNote: Tools > Find Broken Attachment Links…

I know how to fix the broken links and when I perform a fix for the first reference in the Broken Attachements Group, the list of references refreshes and decreases by one reference, as expected. However, if I then fix the broken link on what is now the topmost reference in the Broken Attachements Group, the list does not automatically refresh to remove the newly fixed reference from the Group. It appears that the list of references refreshes just once and not persistently, as might be reasonably expected. This behaviour is reproducible.

Would somebody from Clarivate like to comment on what appears to be a bug?

Many thanks.
