AS I said before, the warnings are legitimate. We (iWAN) do run certain validation checks on devices you try to bring into APIC-EM. Licensing related checks is just one of the items in that comprehensive checklist. The idea of having them as "Warning only" versus "must fix" is something we can deliberate at length. However, absence of such licenses would cause failures in various provisioning workflows downstream and hence we flag and ask user to take care of these warnings appropriately.
Again, the licensing related warnings you are seeing have got nothing to do with the IOS image you have or the APIC-EM version you have. It has to do with actual licenses themselves, on your devices.
A quick check would be to issue "sho license" command on the devices and make sure that the state of licenses being warned about is "Active, In Use". If not, you have to accept the EULA for corresponding license (from configuration mode, execute end user license agreement accept command). Additionally, if you want to move any license from "Eval Only" to "Permanent" use, there's "license move" command for that (from privileged exec mode of the device)
If you want engineering team to help you with having right licenses, that can be arranged; but as such it's a straight forward, self explanatory commands from the device itself.
Once you take care of licenses, and revalidate the devices, you should not see these warnings again.
