Double space key press randomly on Macbook Pro 15" 2018

I just bought the MacBook 2018 15 inch a few weeks ago. I've an issue with the keyboard that when i press space bar once but it pressed twice randomly it doesn't happen every time but very often. I don't how to fix it, so if you guys have any idea to fix this thing. That would be very awesome.

I also found some closed threads on this topic, but the only recommendation was to lower keyboard repeat frequency. Of course I already did that, but it does not help a lot. It looks like a Hardware issue to me. The keyboard repeat delay is so slow, that it makes working very uncomfortable. Especially because I work as a software programmer, that heavily use the keyboard.

cheers
