crosshair does not match with cursor

I usualy play MCPE as usual, with my hands, but recenty decided to use a bluetooth keyboard and mouse. I was super pumped only to later realise that the cursor was not in sync with the crosshair. I had to keep pulling up the menu every time I wanted to move to re-adjust my cursor. I don't really know if this is a bug or not but searched it and found other problems like mine.
