The ELM only synchronizes with Call Manager once every 24 hours, this is why you are not seeing your changes yet in ELM.
To force an immediate resync
In Call Manager
System > Licensing > License Useage Report > Update Useage Details
Then in ELM
Monitoring > License Useage > Synchronize Now
FYI, the License Useage Report in Call Manager is a great way to see who/what is using the licenses. There are links to the right of each license type that will list every device/user that is using that type of license.
Also FYI, that license error is there to give you time to become compliant. The system is unaffected until the time runs out, at which time you are unable to edit some of the fields in Call Manager, but the system continues to run like normal.
