It is more just the difference between UK English and US English, nothing wrong with using either of them this is just one of those things that I wasn’t aware had a different spelling until today.
It is like tyres - UK or tires - US. Tires looks wrong to me because I grew up using tyres but they are both valid spellings of the word.
Dunno how you missed it, it swamped /all for the last two years whilst active.
