The name of the EnderDragon are not showed on boss-life bar.

Last warning, further tickets without proper summary will be trashed.

I don't very understand english :/

You should give the ticket a useful summary. "17 January 2013" is not very useful.

At this moment i'm not in computer only to phone but phone can't edit sumary (android phone).

did it for you

Thanks 😃

I cannot understand this issue.
At the health bar of the Ender Dragon is shown Ender Dragon (see your own screenshot). Do you miss her first name Jean ?

I custom the enderdragon name but the health bar show "Ender Dragon", not the custom name

Got it.
Didn't see at first the name tag.
