Sunder quality not showing up

I recently made a Sunder gem 5 sockets with corruption and realized that the quality buff is not showing up in the skill description, i did notice it wasn't showing up even before the corruption and it was 4 sockets 20 quality.
On the other Sunder gems i press alt and see the quality buff, do i have to worry about it or is it just not showing in the description?

Sunder quality bonus does nothing anyways, as slams don't miss. Per poe2db Sunder has no quality currently, it will be added later.
