Chris (@Crispy) I tried to replicate your scenario on a Win 10 system with PL22.214.171.12490 using RW2(Lumix G9 RAW) one photo with a PL4.3.1 DOP, one with a PL5.0.1 DOP and a further photo with a PL5.0 DOP. All DOPs were original from my files but had to be modified in an editor to set the ‘Rank’/‘Rating’ fields. i.e. as ‘Rank’=3, ‘Rating’=1 and ‘Rating’=5 respectively. I then navigated to the directory in PL126.96.36.19990 and the snapshot is shown below.
This shows the correct star rating for the 4.3.1 DOP but the thumbnails for the two PL5.?.?.? are showing no rating at all!?
This was not what I was expecting. Remaining in the PhotoLibrary and quitting PL5 did not adjust the DOPs in any way, they remained as they were.
Entering the ‘Customize’ screen, “touching” each photo and exiting PL5 also left the DOPs intact.
I am not a novice at “hacking” DOPs but I am tired at the moment (the “excitement” of Christmas obviously or late nights writing posts to this forum (+age)!!) so I might have made an error at some point.
In previous tests where people have lost the ‘Tag’ (‘Red’, ‘Green’ or ‘Grey’) between PL4 and PL5 I used the same type of DOP “adjustments” and included the ‘Rank’/‘Rating’ for good measure and my tests exposed none of the issues others had encountered.
In this case I have not replicated (yet) your scenario but the ‘Rating’ set in the PL5.0 & PL5.0.1 DOPs should have shown up in PL5.1.0 I believe @sgospodarenko.
I stated that I had not recreated your scenario but effectively I have in that 5.1.0 is not showing any rating, any change that makes a DOP update for one of the PL5.? photos will set the ‘Rating’=0. So I forced an ‘Export’ on the first of the PL5.? DOPs and the results are shown in the snapshots below .
I believe we have a bug @sgospodarenko!
