Cause identified to be an issue with the value from the Stored Procedure used for collection. 

The 'timetoexpiration' value from stored procedure 'distribution.dbo.sp_replmonitorhelpsubscription', used for this collection.

It was idenfied that this metric doesn't show expected value.

Disable Alarm 'Replication - Subscription Expiration' or change Alarm severity threshold to 9999. 

STATUS:

Waiting for fix to be released in a future version of Spotlight on SQL Server Enterprise.
