My invoice date shows up red after

in my purchase invoice screen by latest 2 invoices the dates are red i dont know why

Dates are shown in red when they are in advance of todays date, like tomorrow or next week, next month.

na it wasn that either i figured it they payment wasn matched properly

What exactly do you mean by payment not being matched properly? Manager will accept a payment for more or less than an invoice amount without doing anything with dates. Can you show screenshots to illustrate this?
