Unable to model continuous footing under wall

Hi,
I am trying to model continuous footings under basement foundation walls. Most locations in the building, this is working fine. However, at some locations, such as below, I am unable to do so.

What would it take to model the continuous footing? I tried breaking the wall at each column , but that did not help either.

I face the same issue at mat foundation locations. See below.

Thank you,
