Some command/command blocks still using NBT.

Looks like minecraft automatically updated command blocks to the latest system of data.

But for some reason some commands are still using nbt, what confuses me inmensly.

here is an example of a command that shtill uses nbt data and minecraft hasen't updated it to the latest format (this command is inside a command block):

/execute if entity @a[distance=..4,nbt={SelectedItem:{id:"minecraft:tripwire_hook",tag:{HideFlags:663}}}]

/execute if entity @a[distance=..4,nbt={SelectedItem:{id:"minecraft:amethyst_shard",tag:{HideFlags:6366}}}]

/execute if entity @a[distance=..4,nbt={SelectedItem:{id:"minecraft:tripwire_hook",tag:{HideFlags:127}}}]

I have thousands of command blocks simmilar to this one, so plsss fix thiss!! all command blocks changed except this type of commands.
