Sometimes when you click a link you aren't taken to the full-text but to the publisher's homepage or similar.  A known issue with Proquest can see you taken to the wrong article as Proquest sometimes makes a best guess when your expected article is not found. 

If this occurs, please log a ticket on the Hub Service Desk , and include as much information as you can such as the search interface you were using, bibliographic details and the error message / result seen. 

A screenshot is often helpful, and please include your OpenAthens organisation details if possible.

These errors are often caused by issues with metadata or with incorrect open access information and many of these can be corrected.
