Difference in closing price between 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?

17.40 was reached on after hours trading and we don’t have those displayed anywhere else than cfd account same for now ACB price is 16.15 but it is extended hours trading so it is not displayed as well
