hello, this is a default behavior in OPC since in most cases there are no states and in VM core it is not possible to mark one field required for BT while leaving it not required for ST, thus in OPC ST fields are not required by default.
to adjust per your case you can make required ST fields required at OPC Shopper fields section (left menu in opc backend on j3), activate checkboxes under column "Shipping field obligatory" (config is auto-saved upon clicking the checkbox), ideal fields for US are country+state+address_1+city+zip code.
if you are using Fedex, UPS, USPS or similar you may also mark all of the above fields as "ajax fields" which will then update the shipping list per updates in these fields, also updating the last field available to customer within BT or ST section as "ajax field" will make sure that all previous fields are properly remembered when refreshing the checkout page (with another navigation or with F5 key)
best regards, stan
