In my FLow there is only one track appears.

Hey @ivan.sheskin, 

You mean the same song in loop? 

From what device are you playing from? 

Hello from any device, computer or phone no matter what. No, it is not the same song but it is only one track permanently.

You mean one track in the queue, @ivan.sheskin? 

If that’s the case then there is no error, that’s normal. 

If you mean something else, could you please send me some screenshots so we can verify? 

I have never heard of this behaviour. 

Maybe this article can help you:
