Jenkins builds won't kick off automated tests in SpiraTeam

Hello, 

I have a jenkins project set up that is linked to my release in SpiraTeam. I also have a test set in SpiraTeam that is part of the release which contains test cases that were automated using Rapise. However, when I click build in Jenkins and come back to SpiraTeam, it won't execute the automated tests. I have the "Yes" execute on build option selected. Any help would be great. Thanks!
