I have the same issue. The rental property tenant rent due date is the 15th, but every month it shows as the 1st. I go into the edit rental property tenant, select the 15th again (even though the 15th is already set), select ok. It adjusts to the 15th for the current month only and all future months show rent due on the 1st. Very annoying… Also, depending on the date rent is entered, the next due date advances a month. Finally, when rent is entered early, it doesn't show for the month it is intended for making tracking a bit more difficult.
