Rewards and Funding problems

1). Rewards
If I create rewards and save then the rewards show on the front-end, if I then edit the rewards or add a new reward the front-end no longer shows the green Fund this reward buttons

Further, I can NOT delete them to start over!!!!

2). Funding
If I try to test the funding functionality by clicking on a button I am taken to the “How much would you like to contribute?” page

If I enter an amount and click the “Commit to Funding” button, I repeatedly get
The reward you chose is no longer available.

3). Is visual composer meant to work on project pages?, if so it does not, it only shows the shortcode
