All errors of any type are offset in the text. So if it identifies a grammar error or spelling mistake, and you click the arrow to go to the problem OR just click to auto-resolve it, it will go to the WRONG place in the text. It is offset by about 6 or 7 characters. Which means that basically you can't really use any of the tools making it useless.
Happens 100% of the time.
Also getting this on the PC version when using Echo check (see attached). This is 2.0.54.
