Email links no longer working after upgrade to 7.6.2

My ServiceDesk sends out emails to pertinent information regarding a users ticket. In some of those emails are clickable links that the user should be able to click and be taken to the ticket.

In my process those links are setup as

To check on the status of this Incident, please click on the following link;

{ApplicationSetting.ProcessApprover.WebAccessApproverURL$}

This opens this link in IE

https://companyname/object/open.rails?class_name=IncidentManagement.Incident&key=bc216ce4-baeb-4238-941f-d5f5f10c2fe3

However this is not working anymore.

The correct link should be

https://companyname/ServiceDesk.WebAccess/wd/object/open.rails?class_name=IncidentManagement.Incident&key=bc216ce4-baeb-4238-941f-d5f5f10c2fe3

So the link created is missing 'ServiceDesk.WebAccess/wd/'

Any ideas?
