ipad mini 4 external keyboard cursor problem

My external keyboard connects with my ipad mini 4. At first, I thought it works well but the keys on the right do not type the letter or number when I tried typing. The keys on the right instead would move the cursor either left, right, down, up or diagonally. I thought this may be because I connected the external keyboard ahead of connecting my mouse but I tried forgetting both devices and changing the sequence of connecting but still, it does not work. I tried turning my device off and reconnecting to no account. My iOS is updated for my device, it's on iOS 14.6, it's supposed to be compatible with external devices. My external keyboard works well when connecting to other devices such as my laptop and my phone.
