@Gsintes is correct - you have ordered the wrong type of license. If you contact the Cisco reseller you purchased them through, you should be able to RMA ('return') the Systems Manager licences. You will need to order MR Enterprise licences, as suggested (notice these are what was used previously to license your Access Points in August 2018 and November 2017).
You could order longer durations than the one year indicated; they are lower cost per year that way: 3, 5, 7 or 10 years are available.
