Thank you An613!!
I had the same problem. Thank you so much. It is not you, it is the programming.
Deleting the CCA section in the rental summary page worked for me. I also didn't go back to the summary page.
Hey Intuit. You have a bug here. It has something to do with entering a "0" CCA class automatically when an entry is made (or created automatically) in the CCA section.
Cheers,
