"Home Mortgage Interest Worksheet" errors

I am working (around) your bug regarding multiple 1098 forms. I am consolodating the two forms I have and that seems _close_ to working except: the form is accepting information about how the cash out was arrived at (the sub worksheet with itemization of the expenses related to house accq. etc. so the remainder can be identified.

BUT the "Home Mortgage Interest Worksheet" wants to call the out standing principal at 12/31/2019 the "Beginning Balance" in F3. Which makes no sense. I cannot tell where that number then comes into play but it is wrong and that can lead to no good outcome.
