It is normal as KMS activation is only valid for 180 days.

"KMS activations expire after a set period (180 days). The “activation count” will automatically increase on the Software Licensing server and the client will see itself as not activated until it reconnects to the server and reactivates. The advantage of this method is that you can’t permanently waste KMS keys through a constant cycle of re-imaging or OS reinstallation. Eventually expired activations return to the KMS server and increase the available activation count. The disadvantage is that KMS clients must reconnect to the licensing server on semi-regular basis. Configuring clients for KMS activation ( and the required KMS infrastructure on your network) is most appropriate for client devices that rarely if ever leave the corporate network."
