Difference in closing price NYSE & T212

Maybe I’m missing something but the closing price (21st May 2020) for ACB (Aurora Cannabis -NYSE) shows as 17.40$ on all external/independent charts but on the T212 Invest platform (apparently displaying NYSE data), it shows 17.17$ (sell 17.16$/buy 17.17$)
Can anyone please explain this?

17.4 is extended hours price from yesterday which is not displayed in invest account
