use this function to delete: https://sampwiki.blast.hk/wiki/Delete3DTextLabel

But i myself just delete the label by updating it to "nothing".

pawn Код:

Update3DTextLabelText(labelID, 0xFFFFFFFF, " ");

I would recommend you to create the labels for every player under OnGameModeInit and then simply use the update
function in order to edit/delete them.
I also have had simillar issues in the past trying simply delete them. (Somehow the label IDs got messed up i suppose).
