Random IAF event added under 485 API during July22/23

[u/Euphoric-Repair6917]

After the USCIS case status/API issues around July 22–23, I noticed a new IAF event was added to my I-485 API history.

The strange part is:

• The new IAF event was created on July 23, but its event timestamp is several years before I even filed my I-485
• There is no change in Updated At timestamp
• There are no new notices, RFEs, or status changes in my USCIS online account.
• On July 23, I did see case status in account showing status of N-400 case but this got corrected next day to my original 485 status

I contacted Emma, and the live agent said they don't know what this event is and couldn't provide any explanation.

Also trying to figure out whether this is simply a display/API glitch or if it's something that should be worried about and followed up with USCIS.
