No smoke grenades on Support Loadout 2 slot

Dear BF Devs,

Firstly, thank you for finally making a sequel to BF4 ;) I have been a big fan since BF3. 

In the Loadout 2 slot for support there are only frag and incendiary grenades available and no smoke. I have checked the other slots for all other classes and all of their grenades are available on each one so this seems like a bug to me.

I am playing on Xbox so I’m not sure if this is present on all platforms.

Please can you fix it? I would like smokes on all my support loadouts :)

Many thanks in advance!
