Hi,
HikaShop will display all the shipping services that UPS returns back among the ones that you selected in the options of the UPS plugin.
So either you didn't check the correct ones, or there is some other setting which prevents UPS from proposing UPS Standard and UPS Expedited. Some might only be available for certain destinations, some only up to a certain weight/volume, etc.
I would recommend to contact your UPS technical support with a screenshot of the settings of your UPS shipping method and the weight/dimensions of the product you're using for your test so that they can check that the settings you entered are correct for what you're doing.
