Thank you for your attention to my question. I was able to find the problem but it did not have anything to do with the browser. This is how i fixed it:

In settings, went to "all lists"

Selected "terms"

Clicked on the dropdown arrow for "Due on receipt"

Found that the setting was for the 1st of the month (due on a certain day of the month) which was not what i wanted .

Selected "Due in fixed number of days" and chose "0".

Now my invoice due date matches the invoice date which is what i wanted for "due on receipt".
