Nametags given on my entities keep disapearing

[TheRPGAdventurer]

    @Override
    public ITextComponent getDisplayName() {
        // return custom name if set
        String s = this.getCustomNameTag();
        if (s != null && !s.isEmpty()) {
            TextComponentString textcomponentstring = new TextComponentString(s);
            return textcomponentstring;
        }

        // return default breed name otherwise
        String entName = EntityList.getEntityString(this);
        String breedName = getBreed().getSkin().toLowerCase();
        ITextComponent name = new TextComponentTranslation("entity." + entName + "." + breedName + ".name");
        return name;
    }

i was once using the getname() method but that was deprecated so likely the cause of disappearing nametags. Now i replaced it with getDisplayNAme, but it also happens.
