Multiple Origins for Cloudfront, not allowing me to change Behaviors Order

When you have only two cache behavior, you can't change the order because the default one is always the last to be processed. Could you share a bit more details on what you're trying to achieve?

You have two buckets with same folder structure ie /wp-content but the path pattern when configuring the behavior has to be unique and the first origin created would map to the default (*) path. The closest you can come to changing the order is to swap the origins for paths with precedence 0 and 1 (in behavior tab). That would also reverse the path pattern mappings. (so you need to understand what you want to accomplish in terms of path pattern matches by changing the precedence since it's not clear with info provided)

You can also add a path pattern for bucket 1 and bucket2 respectively and leave the default path set to either of the buckets. But again that depends on what path pattern matching you want to set up.
