Enroll button in the Specialization does not work

Hello.

We have a Specialization that has multiple Activities (Courses) mapped to it. If someone gets assigned to it (recommended assignment), then clicks on one of the Activities (courses) and then the Enroll button in the Available Offerings section, this one does not work. If clicked, you can see it was clicked as it gets grayed out but it does not register the Enrollment. It does nothing. What works is clicking on the left hand side of the button, on the actual available Offering text.

Did anyone else encounter this presumed bug? Is there a way to fix this perhaps?
