Double space when i'm typing

Hi, when i type i get a double space. As you will probably see in this text, there are two spaces automatically being entered even though i only hit space once.!!!

This is present when i’m using my online email account, libre office, even i n this forum it happens!

I’ve tried all sorts of setting including the repeat speed etc.

How do i fix this!!! is no use typing in the way !!!

I have a herobook pro by the way.
