Trying to start a new sprint and get warnings

[Anastasia Seidaridi]

Hello all, 

So we are trying to start a new sprint and get some warnings regarding some tickets that are from another project. Any ideas?

I found this article here, saying that this is caused by sub-task issues associated with story points, but this is not the case for us. Two of the tasks mentioned in the warning are Story & Task. Also, the sub-tasks have no story points assigned.
