The number of rewards seems to be limited

I’m trying to set up a crowsourced fundraiser, but it keeps limiting me to 11 rewards and we have more than that available. Also, it keeps re-ordering the rewards in ways that don’t make sense. It should list the rewards from least-dollar-amount-donated to greatest, but instead it seems to be sorting it according to the number the donation amount begins with (e.g. grouping all the $1xxx rewards together, and then all the $2xxx together, etc.), only this isn’t really consistent either. Finally, it does not seem to want to remember that I told it to display the rewards panel on the bottom instead of the top — it keeps trying to default to the top after I save it.
