Not compatible with Germanized

Dear Support,

i tried to clarify some issues with my checkout fields.
I’m using the Pluging Germanized Pro for some other functions, but there is one option which adds an extra field to the checkout for checking the VAT Number. When i use Germanized with your Plugin the extra field disappears. I tried with some other Check Out Editors: There the field doesn’t disappear but i could only solve my other issues with your plugin.

But i don’t want to dispense with VAT function from Germanized. Is there any possibility to make this two plugins compatible?

Thanks a lot
