Not sure I understand your issue because I don't know what is "similar" in your entry and what you were expecting.
If this is the issue: date number you look at are "epoch" time. 1686237900? =? June 8, 2023 3:25:00 PM
If need help see
IB doesn't always use "YYYYMMDD" sequence on historical when requested timeframe below day, it then switch to epoch time.
Not sure there it's flagged
I detect that easily, for the next coming 13 years the first char is a 1,
anyway epoch is always 10 chars for next 200 years, if use sub-second resolution like in 1686237900.1234 , the '.' is the mark of it
I am more concerned by the "?" in your entry, this value are typical of buffer cookies and may flag that you are having a buffer read overrun or something alike.
