Thank you for your report!
However, this issue is Invalid.

Your game, launcher and/or server is modified.
If you can reproduce the issue in a vanilla environment, please create a new ticket - this is a bug tracker for the game, and not a support website.

• Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang Studios or the Bugtracker.

• Any plugin or resource pack issues need to be addressed to the creator of the plugin or resource pack.

• If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run extensively modified server software.
