On books that were marked as started via Kobo Sync, it seems like the started-to-read date is not always being set correctly. It seems to be using the date the book was purchased in Kobo instead of the date I started reading it.
The books I’ve had issues with were sync’d across on the same day I started reading them. I suppose there’s a possibility that StoryGraph is picking the wrong date, but I suspect it’s more likely that Kobo is sending the wrong date, and this bug will need to be passed on to them.
An example: the book I’m currently reading (Half-Made Girls by Sam Witt) was purchased on 16th November 2016. I first started reading this on 2nd August 2026 (so it’s not a case of a re-read causing problems) and I let the Kobo sync mark it as currently reading. I would expect it to have a start date of 2nd August 2026, but instead it shows as 16th November 2016.
