I suspect that each time you tried to cash out, a different SWAB was assigned to review the cashout. (That's Slob With A Job.)

On your fourth try, you got a SWAB who hadn't had enough coffee yet. Congratulations!

But you may not be able to get lucky cashing out again. . . you should probably deal with that issue rather than playing on. It will all be zero-profit play if you don't deal with the problem!
