I have a prob for join random room

I set the customprops.I get the room's customProps in room is right, but it is empty in outside.

print（inroom）：Room: '00000000000000E0' visible,open 1/6 players. customProps: {level1=1}

print（out）：Room: '00000000000000E0' visible,open 1/6 players. customProps: {}

So player can‘t join in room.
error：Operation failed: OperationResponse 225: ReturnCode: 32760 (No match found). Parameters: {}

Please for hlep.Thank you very much.
