tf300t dock not working properly

[gage311]

Ive had my tf300t 32gb for a while now bought it refurbished on newegg and i love it. so naturally i bought the dock to go with it. everything on the dock works perfectly the usb, the battery, charging, touch pad, and all they keys. except the keys don do what theyre supposed to. for example if i type "p" it brings me to the home screen, back space gives me a " ' " i tried factory rest with the dock attached with no luck. my tab is rooted with twrp but no custom roms (couldnt get any to work but thats another story/ fourm) any thoughts or ideas?

Where did you buy the dock from?
What is selected as default language in Settings>Language and input?
You may want to try Keyboard Manager from the Play Store. It let's you select which keyboard and layout to use for the hardware keyboard or software keyboard in landscape/prtrait mode. Choose the Asus keyboard for hardware.
