Add-on "minecraft:nameable":{ "alwaysShow": true } bug.

When I'm trying to create an Add-On where mobs names will always show like players do. It doesn't work. I changed:

"minecraft:nameable":{
"alwaysShow": false
}

to

"minecraft:nameable":{
"alwaysShow": true
}

When I name the mob with a name tag, it does not show the name except if we look at it, even though I already changed the behavior pack of the mob.
