Hardcore spectator

I changed a hardcore world to not hardcore using nbteditor on a server and now when I die it still sets me to spectator mode, however my hearts look normal and the difficult isn't locked to hard.

 

This is a server, if this isn't an issue im sorry.

I know that we aren't technically supposed to be able to change a world back to survival but its a server and people voted against hardcore forcing me to change it back
