Fulfillment staff can't purchase UPS labels, only USPS (using Shopify Shipping)

[SuzanneFontaine]

Hello! My two fulfillment center staff members are currently unable to purchase/print anything other than a USPS shipping label using Shopify Shipping rates. I'm trying to figure out how to give them permissions to purchase/print UPS shipping labels using Shopify Shipping rates (I don't have an account/negotiated rates with UPS).

Attached is a video of my fulfillment guy showing the issue he encountered. They don't have this problem when trying to purchase/print a USPS label. In the Users and Permissions settings, I have already checked "Fulfill and Ship" and "Buy Shipping Labels" for both of them.
