Problem with tags count of license 5000 tags

This can certainly be confusing, but the installed license is for 5000 tags. However, the licensing technology allows a "pool" of tags to be available and to add to that pool (I'm not aware of any current licenses that take advantage of this). To support that, the Historian reports "in use" counts to the license server in lots of 50. Based on the "In Use/Total" column shown, your Historian currently has 3201-3250 licensed tags and you have at least 1750 more available in your current license, 

UpgC, Historian 2023 R2, Standard, 5000 Tag 

This is the license I'm using
