Entering Cleared Raid Issue

Tonight (before impromptu maintenance), I entered Naxxaramas. I hadn’t realized which character my raid lead invited me on (he invited on a character that cleared last night). After the load screen, my character had the “0 exp” in purple text pop above my head and my in-game tutorials turned on. (I think I heard the sound of an accepted menu click).

I was not prompted whether I wanted to accept the 15/15 lockout. When my raid lead mentioned it was his, I immediately hearthstoned back to lights hope chapel. I checked my raid IDs and I am now saved to the full cleared Naxx.

I think there must be something going on with the lock out prompt that when you enter it auto-accepts. I know it’s a long shot - but if you could reset my Naxx ID that would be appreciated.
