Why

This might be a glitch or an issue on your end, if you relog and play skywars again and the issue is consistently there then I would assume that it is a bug. Thus you would need to report the bug here, make sure to select "MCO/Bedrock" as the platform and fill out the whole form, prior to doing so read the bug reports guide here. If you're still confused, shoot me a PM!

 

As Abood stated, it may be an issue on your end. I would submit a bug report here if it did continue to happen. I've tested it myself and it is working fine. Lag might be an issue for you, make sure your connection is stable and try clearing your cache. Resetting your router wouldn't be a bad thing either. Since your concern has been addressed, I will be locking this thread. Please message me directly for anything further. Have a nice day!
