Indeed, this is confusing and has been solved in 2018.1.3 version. The real expire date in your case is the one in Studio (Expires in 33 weeks).
In the release notes for 2018.1.3 version it is stated that “The get-info Regutil command now also displays the date on which your license expires, in the Subscription expire date field”. https://www.uipath.com/release-notes/uipath-v2018.1.3
License expire date that you currently see is in fact the next time the license is going to be checked by the licensing server. By default, this is checked every 30 days.
