Inconsistent final outcome for BTC 5-min UP/DOWN on polymarket

Trading Strategy


Anyone has experience trading on polymarket? 
i encounter a very strange behaviour for 5-min BTC UP/DOWN marekt. On polymarket website, the initial price is 75,027.53 and chart show 75,009.03 at period end. I expected the final outcome should be DOWN
However, polymarket mentioned it is UP with final price "75,065.44" instead of "75,009.03". Why the result is not consistent? Is it a bug or I misunderstand something? 

In fact, I encountered multiple times for this situation which lead to some losses...
