Axis SP AA LVL 4 wrong picture or name

The lvl. 4 Axis SP AA has the wrong picture or name, in the picture you can clearly see a SP AA with only one cannon, that is the Ostwind NOT the Wirbelwind. The Ostwind is the more improved version of the Wirbelwind (the name under the picture). The WIrbelwind however has 4 20mm cannons not one 37 mm like the one in the picture. I hope this will be fixed
