ML Skill extracts same date value in different formats

Hello,
I’ve created a ML Skill that works great until now. I have a table with items and each item has a DATE field. I’ve noticed that for one of the documents the dates are always wrong after the third page. Even though everywhere the same date is written (2023-05-12), on the third page the dates suddenly become (2023-12-05)
I have no idea why that is. If anyone has any hints as to why this is happening I would be very grateful.

Thanks in advance,
Dan
