Cover 4 Willie GLITCH!!??

Im running into a cover 4 that turns into a cover 4 Willie??

The setup is a Gun tight audibles to any random formation not like Gun tight; pulls the deep left corner to the right side, and puts the defender into a man D. So cover 4 zone defenders become 3 man defenders; DB 1-3 become man. The coverage shell on Cover 4 is set for default.  The amount of defender movement during that whole play is worse with the cover 2 man coverage shell.

 Anyone else run into this glitched BS?
