The 4hr Candle formation on MT4 and MT5 platform is not the same

 
I am a new trader and  using MT4 and MT5 platform. yesterday, I  observed that the 4hr Candlestic formation at MT4 and MT5 is not the same. (I think the issue happens due to how they combine the consecutive 4 hrs)
 
They must not be same because the price/quotes are going from different providers to the brokers (the brokers are responsible for the price/quotes and so on).
