It is annoying. I have done all the team goals for all teams except one. For the last one I have 5/6 team goals so there are 2 events left and I don't know which one will grant me the last team goal. I think they will change this in a patch. At least they are working on changing the looks of the career mode to make it a bit clearer and better looking. This issue with team goals will probably be fixed so that you can see which events actually has team goals and which don't and which team goals you have cleared or not.
