username: Dalek_Destroyer1/____Cyber____/Cyber_leader11

Problem?: my name hasn't changed from when i changed it

Description: When i first got onto the server (In December) my username was gamerdude1103. i changed it to dalek_destroyer1 as i was spending my time only on the server, and it changed perfectly fine. then in January i changed my name to Cyber_Leader11, but the server said my name was only cyber_leader11 in TAB, And in chat my name was still dalek_destroyer1. then, recently, i changed my name to ____cyber____ and it does the same thing, i know this probably be in the bug reporting section but i thought it would be better to post it here.

Anything else?: This is really confusing for people (including me) also when i see othr people changing their names it works (Most of them)

This isnt really a bug but the server takes your minecraft name as a nick so when u change name u may do /nick remove to change it to the new one

Well is there a way for a staff member to get rid of my nick since i do not have the permissions?

 No sorry only You If u Get Donatorer or up can do it
