I was able to get Sell Mode, Rent by day and Rent Length, Ask to work as you described. When I enter 1.99 for Rent price, 1.00 is inserted into the product instead. Following your example, I chose Options, 12 (for Out of stock, Hold), but Service, Discontinued gets checked and when I tried and Options, 13, Hide from WebGen get checked but never Out of stock Hold? I have made sure that all fields are set to general text.
