I got a Glitch need help

[theroc44]

Hey guys i upgraded to the ix/2 turm in the game but only the deck gun and light flak option is showing up. Something must be messed up just dont know where to edit the uboat static gun settings in the game file. I looked thru the save folder and i found the file playersettings and it only shows one flak gun. Does anyone know how to manually edit which turm is on your uboat and how to edit the flak guns thru the game folders? Thanks just sucks cause i can use a heavy flak gun for the first time and i cant even equip it.
