We were given four fast passes this past sunday as well.
I had originally booked
Space Mountain
Haunted mansion
and big thunder
and was given a duplicate for space moutain as our 4th fastpass I changed the first space mountain to jungle cruise with no issue and all 4 fastpasses worked this past sunday may 4th
one of the cast members said that due to the fact the system was down when they announced the 7DMT they were giving guests and additional fastpass since you could not access
