Cant find F14 F15 brightness control in newer macbook pro

[davehan]

Upgraded to 2018 Macbook Pro running Mojave 10.14.6, got a logickeyboard (pro tools version) plugged into the macbook pro (via hub). Noticed F14 and F15 default to brightness control on the external keyboard. I used them for other pro tools functions in my older laptop setup. I cant find any way to change this in this MBP -

I see on google searching, older OS versions had a "display" option under OS keyboard preferences where you could shut down this F key assignment,

but mine has nothing that refers to this and those specific keys.

Anyone running hardware like mine have a solution to this?
