Data Store multiple player loading problem?

When multiple people load at the same time, it will take a value and duplicate it into one player's inventory. Let's say two people join, the intvalue will be created two times in a player's inventory. A player that is joining, ofcourse. And the other player that was joining does not get that intvalue. It just gives it to the other player that was joining at the same time. Does anyone know a fix for this bug? line 19-20
