Can you please capture one or more images of the parts of your Quicken window showing the issue (loan setup details, payment schedule, scheduled reminder details), sensitive information blacked out as necessary to protect your privacy but annotated to describe the situation, and attach the image(s) here?https://community.quicken.com/discussion/7867159/faq-how-do-i-post-a-screenshot-in-the-community-from-windows

Please save images to files of file type PNG, JPG, or GIF only. They're easier to work with than PDF files.
There may be a disconnect between what the payment schedule calculated (every xx days) and the scheduled reminder's future iterations properly scheduling payments every (e.g.) 1st and 15th
