Strange Glitch with selecting words

Hello, recently I’ve experienced a very strange glitch, basically when I highlight a certain word I would like to either replace or change it doesn’t actually change the word I’ve highlighted but instead the next word over.

I’ve provided a visual example of what I’m talking about, as you can see I’ve highlighted the word sound in my text, yet for some reason it’s skipping over to the next word which in this case has herself, even though the word is not highlighted.

Also I think this might be a glitch exclusive too Google Docs but I’m not too sure, either way it’s a weird thing that I’ve noticed and is incredibly annoying.
