Keyboard inserts random full stops when i press the space bar
I have a . MacBook Air (Retina, 13-inch, 2018).
The keyboard started to insert full stops when I press the space bar. I do not know how to solve this but it is actually pretty annoying.
I already checked the input sources in the keyboard system preferences and there is nothing . wrong there.
If someone could please help me it would be really appreciated.
thank you
