After updating to every file shows as changed

Duplicati now thinks every single file has changed since I updated to today - and if therefore insanely slow. Every file in the Live Log show something like this:
True, size changed: True, metadatachanged: True, 4/28/2018 4:27:25 AM vs 1/1/0001 12:00:00 AM

The date is always 1/1/0001 12:00:00 AM for every single file in my system according to Duplicati. Obviously that’s not the case so this must be some kind of bug somewhere.

What version did you update from?

I seem to recall there being a metadata bug in an older version that has since been fixed and this recheck of every file might be re-alignment with the correct code.
