Can't Find Affiliate Area for MarketPress Add-on

So I'm trying to add an affiliate commission of 75% for my Facebook Ads Course on my site but the documentation says there should be an "Affiliate Section" under the MarketPress store settings after the add-on inside of Affiliates has been activated.

I have activated the add-on,
can't find the affiliate settings in MarketPress store settings.

The documentation I'm referring to is here --> https://premium.wpmudev.org/project/wordpress-mu-affiliate/#usage (scroll down to "MarketPress Add-On"

It says I should see
"When the MarketPress add-on is activated, you’ll see a new Affiliate Settings section in the MarketPress settings at Products > Store Settings > Payments."

I've confirmed that the add-on is activated (screenshot below) but don't see it in the payments section or any other section for that matter.

Thanks in advance for any help.
