DB versus DOP:-
I cleared the database and navigated to the Tulip images shown above and took a snapshot of the DOP elements of interest and the Database. The 00 on the ends of the Uuid fields highlighted came from my “hacking” that caused the results above. Accepted as normal fields when the new PL5 absorbed the DOPs into its empty structures.
I am afraid I do not know where the other Uuid fields come from nor what they are for but I do know if the ones highlighted get out of step with the database then VCs are the result. The ‘StoreSettings’ field holds the edits either created during an edit session or taken from a DOP as appropriate.
[Additional material I had tacked onto this post has been removed because the problem I reported appears to be related to the re-use of the same (or very similar DOPs) and needs more investigation. Tests on “real” photos and their DOPs (actually created by DP4) did not exhibit the same behaviour!]
