Bad update (v5.0.7)

I have many problems after upgrading to 5.0.7. So I downgraded to v5.0.5:

Problems:
– Appears a lot of Order 0$ in the dashboard
– Orders are paying successfully (“Order & Payment status” completed) but the product name does not appear inside (like an empty cart) even though Total Price is available
– Users cannot download files for orders created by admin for them (5.0.5 & 5.0.7)
