It seems as though the keyboard predictive text is rather glitchy. I was talking to my friend about something on Ark: Survival Evolved on my PS5 and it auto replaced "fabby" with "flabby". When I tapped the word to revert it, this code came up. Bit strange but hey ho.
However, sometimes if I go to correct spelling or tap the word to correct it or put it back, it deletes the whole word and any word next to it.
