Captions sometimes saved in raw, sometimes not

Well, the captioning is getting wonkier & wonkier. I accidentally gave the raw file a star rating, and that wiped out my caption. I tried giving my jpg a star rating, and THAT wiped out the captioning too.

Not sure why the write caption feature is so fragile. I’d written captions for 2500 files and many of the captions are missing now. Would it help to download a new digiKam to see if its caption feature works better?

It probably DOES have to do with “wroteComment: false”.
