Thanks for posting about this error. We do our best to keep our preview page updated to represent the variety of listing options available as closely as possible, but doing so is an ongoing project and there are currently a few things we are looking into with respect to that page.
I am not confident enough that I fully understand the discrepancy you described to confirm whether it is something we are already working on, but we will be happy to look into it further if you can provide us with some additional detail.
I recommend filing a support case about this issue by mousing over the “Help” tab within your account and selecting the “File Support Case” option. Just be sure to include a specific example of a listing in which you are seeing this behavior to ensure we are on the same page.
