When taking payments on a ledger of a patient who is on a payment plan, the "apply to payment plan" box automatically checks itself. It is hard to catch every time, so payments are applied that shouldn't be and that messes up their payment plan and drops them off the payment plan manager so their monthly payment is missed. Patients with payment plans still get work done in the meantime so this happens quite often and has been an ongoing issue in our office.
Thank you for the recommendation, we will consider this for a potential future release.
