Her stock 8cm green is a secondary, so it will work as a double attack.

12.7cm単装高角砲 is the green weapon that comes with Yuubari, 12.7cm連装高角砲 is the more common AA gun, somewhat more likely that you were using the latter and not the former.

If you're still not sure which you're using, please take a picture, but from your current setups you're using the standard 1x main+2x secondary and 1x main+1x secondary double attack composition.
