In Bridge 2020 (10.0.0.124) on Mac OS 10.14.6.
On many occasions, the star ratings and labels disappear. For example, if I apply a batch job or when copying files to another folder by dragging. (I do batch jobs where I modify the originals.) That happens to JPGs. And maybe RAW files.
The raw metadata is quite modified when I look at File Info.
It used to not be a problem but started with Bridge 2020.
First time I face so many bugs with your products.
