I am trying to select a few allowed shipping methods under UPS in the Magento 2 Admin.
I tried selecting the ones I want (e.g. UPS Standard, UPS Three-Day Select, UPS Next Day Air, etc) by holding the CTRL button and clicking each one. The ones I want change blue, and then when I click away they turn grey like they are supposed to. But when I click Save Config, it reverts back to selecting all the UPS Allowed Methods.
How can I fix this?
