My Gnucash version is 4.4 (more specifically 4.4+(2020-12-28) running
on Debian); thanks for reminding me to mention that, Stan!

Jean, I tried setting the payment frequency to monthly, leaving
everything else exactly as it was. All of the payment amounts remained
exactly the same; only the dates changed.

The formula showing for "Amount" is exactly the same as before.

Assuming that my hypothetical monthly total payment, interest portion,
and principal portion should all be 26/12 × my actual biweekly amounts:

* The total payment amount is roughly 1.75× what I would expect;
* The interest portion is about what I would expect;
* The principal amount is thus way too high;

Let me know if there's any more info I can provide.

Cheers!
 -Chris
