Preview 5: Metadata disappears after adding a rating

Observed behavior

Hit CTRL+3: Metadata below image from eg f/3.5 etc changes to f/0.

Expected behavior

File metadata appears to still contain f/3.5. However there is no entry in the ‘windows default rating’ metadata, which I would expect to contain not 3 stars.

Steps required to reproduce

Operating system/Hardware used

Windows, see also send in log.

Confirmed and fixed for the next release!

Internal issue number is #509.
