Why is there a difference in price between the lite and Pro for eth and btc?

Can anyone explain why there's a massive difference in price between the market listing on Binance lite vs the actual price I can get for the currency?

At the moment, for example, the lite version lists eth as going for £1,542 - which is the same price as is listed on google - whereas when I try to sell it, I get closer to £1,450 which is also the price listed on the pro version...?

Sorry if I'm being a moron, buy I've searched for answers and can't find anything.

Thanks if you can help ????
