CFD Template error

Hello this is Sammed Vankudre from Team Kratos Racing Electric.
I was doing a simulation whose procedure is given in CFD Analysis Advanced from Formula Student Electric course.
There I selected FSAE Full Car CFD Template with help of Catalogue Browser.
I followed the exact procedure but following error of Multiple boundary conditions is occurring.
In the picture attached below we can see that there are no common supports. What should i do then?
