Both pieces are in the slot: the edge is solved, but the corner is twisted with white facing you.

Your algorithm backwards
R U2 R U R' U R U2 R2
solves F2L 39
That's why your scrambles are never the inverse of the algorithm: you'd be practising F2L 39 without knowing it. CubeDojo builds a random state with this case and checks it comes out.
