Issue with workspace seat types getting changed by the system

I’m not sure if this is the right place to post, or if anyone else has run into the same issue. Our workspace just renewed the Business ChatGPT & Codex plan this April. In June, we bought some Codex credits. After that, I adjusted the workspace settings under “Monthly usage limits” → “Per user override” so that only 2 members have a quota to use Codex credits, while setting the quota for all other members to 0. I didn’t set any of the member seat types. But the next day, I found out that everyone’s seat type had been changed to Codex. Now, changing it back to the original ChatGPT seat type requires us to pay again. Which of my actions could have caused this? We even have one member whose account is still disabled. After the last automated moderation error blocked us, everyone else got unlocked successfully, but that specific member is still blocked. We already submitted a case, but we know it’s going to take some time to get a reply.
