I can solve this problem by using other cards (for now

I think the issue (or good thing) here is that it depends on Plastiq to determine which payments should be considered to be mortgage payments. So, if Plastiq is not aware or is not sure about your bank, it will allow it. For large banks (Chase, Citi, etc), it is a no go.
