Deleting edges with Zmodeler brush

Hello,

What is the easiest way using the ZModeler brush to delete the edge indicated below in picture A?

My best guess was:

ZMODELER > EDGE ACTONS: Delete > TARGET: EdgeLoop Partial

This, however, is not giving me a desirable result (please see picture C).

Is this a bug perhaps? If not, what is the most direct way of deleting edges like this?

Thanks!
