Hello, thunkbale community, i am currently working on a multiplayer quiz game, where two users can play global quiz with each other.  
So, for doing this, i am storing their user IDS in an object `Waiting` in firebase, and then when there are 2 participants in the Waiting, i am collecting their IDS and making a unique match id of 8 chars using random chars, and then storing the match id as value of their user id in a new object `Players current match ID`  
I have two demo users now, one with user ID: `o9=>i!tk` and one with  
`{&,v<9;*`  
Now the problem is that, when i store their user IDS in players current match ID, the user id `o9=>i!tk` stores wrong ID, can u please help.

Some screenshots for more information about code and result

The Firebase result is like this:

The random match ID stored in `o9=>i!tk` is wrong and that of other is true,

Can anyone please tell why its happening?
