Default arhd71.1 broweser and keyboard

Hi ive installes 71.1 on new phone i received today. I s-off with rumrunner. Have twrp installed. Latest firmware from arhd website. All works fine apart from when i use the keyboard on browser. I use the mobile page of fb for example. Try to type and on arhd 31.6 the keyboard appeared and the screen moved up so u could see what you was typing. On this version it doeant do this. Have full wiped twice incase was a rom install fault but no luck. Only way i can see what is being typed is by closing the keyboard. Checking then opening keyboard again. Type blindly and check again.

Does anyone know how to fix this pls
