Periodic boundary condition in COMSOL 43

we have recently upgraded to COMSOL 43 and I am trying to setup a periodic boundary condition for a unit cell under the structural mechanics module. The source has displacement u and v, where the destination have u*exp(i*a*k).
I thought I'd choose Floquet Periodic condition, yet I keep on getting "Multiplication Failure, matrix dimensions must agree".
Could someone point out what I did wrong?
Thanks a lot.
