Internal windows / geometry error

Hi,
I do encounter problems when trying to apply correct boundary conditions in a simple model involving 3 storeys of office space and a side atrium, separated by internal windows and an air wall (lowest level).

Specifically, I receive the following error message: “1. Number of windows doesn’t match between Atrium_N_Srf_0 and OfficeMid_Srf_2. Make sure adjacent surfaces are divided correctly and have similar windows.”

I am not sure the order in which I added glazing and solve adjacences is correct, but could not find clear guidance on it.

Thanks!
