Reverting did solved the problems, however. I did also a DB check with the Kobo plugin and it was ok. No idea how thoroughly that check is, though.

It happened for other books as well.

Agree. But: I always make sure to delete first, then add the same book again, just to avoid mentioned DB issues.

I have none kepubs, all are calibre certified sideloaded epubs.
Sure, the above checks does not rule out problems completely. There might be some unforeseen combination. However, for me this is the first time I saw the marking issue at all so I immediately noticed it. Strange that is seems a known problem within earlier FWs.
One warning though:
I got FWs 4.14.12777 and 4.15.12920 OTA. To revert to 4.14.12777 I downloaded it from the mobileread patch (wiki) locations and got a 7-zip warning about "There are some data after the end of the payload data". I tried 2 different download locations, same error. Previous FW versions do not have that. It might be false alarm, but better safe than sorry.
