Hi Daniel, and welcome back.
The issue is that you took the exam before you rejoined VATUSA. Technically, at least according to our web system logic, that means it didn't count. If I were just joking around, I'd say that it was a good practice run before you took the one that counted.
I'm a little perplexed about your assertion that you requested a facility assignment. You were not eligible to, as evidenced by the red x's that you saw. And your record doesn't show that you requested a facility assignment (which it shouldn't!).
In any case, I waved my magic wand and waived the exam requirement so you don't have to take it again. Payment for that is a 1L (or larger) bottle of Jack Daniels, or a roll of "nice, soft, not that substandard stuff you find in public venues 'cause they're cheap) toilet paper.
Now all you need to do is go request the facility assignment.
Again, welcome back!
