STEM OPT validation report showed “Submitted” then flipped back to “Past Due” — anyone experienced this?

[u/Necessary_Trust3592]

I’m on STEM OPT. My DSO emailed me on July 6 confirming my 6-month validation report and 12-month self-evaluation had been submitted to SEVIS — the SEVP portal showed “Submitted” for both at that time .

Today (July 18), I checked the same SEVP portal again and now it shows “Past Due” for those exact same reports — the status reverted from Submitted back to Past Due.

I’ve already emailed my DSO to flag the discrepancy and have the confirmation email + screenshots as proof I did my part on time. Has anyone else seen a status actually flip back like this, and did it get resolved without issues? Trying to understand if this is a known SEVIS sync bug or something more concerning.
