Conflict with BluTooth keyboard

I have a Bluetooth keyboard that I use with my IPad Pro. 

I use Swfitkey as I type in both English and Italian.

But Swiftkey is only allowing me to type in Italian on the external keyboard, i.e. the keys are being configured like an Italian keyboard instead of like English UK (or even US, I know both!)

How do I tell the external keyboard which language to type in when?!?!

Right now I’ve uninstalled SwiftKey as I type a lot more in English these days and I don’t know the Italian keyboard all that well!!
