"Delete Imported Data" don't work

Hi,
I have just imported my Limitless Data and an error “XXXX files failed to process” is displayed.
I remarked that the conversations seemed imported in my lifelogs by the way. But I didn’t know if it’s correct or not. I try to use the feature “Delete Imported Data” and it displays “Delete 0 Limitless conversations”.

The Limitless conversations are still there in my lifelogs.

It’s annoying because I uploaded my lifelogs several times by trying smaller ZIP files.
And now, I have duplicates in my lifelogs.

So this feature doesn’t work properly.
Best regards,
Florent.
