Summary:
The inline help for behaviors in the betas of the Branch Source plugins don't quite match the options shown in the drop-down menus they are intended to provide help for. For consistency sake, I feel the headers shown inside of help text should match the options in these dropdowns.

Steps to recreate:
1. Configure a GitHub Org Folder job.

2. Under Behaviors --> Discover Branches --> Strategy, observe the options available in the dropdown. They are:

• Only branches that are not also filed as PRs
• Only branches that are also filed as PRs
• All branches

3. Now, view the inline Help. The headings are as follows:

• Exclude branches that are also filed as PRs <-- This is different from the dropdown
• Only branches that are also filed as PRs
• All branches

I feel it would be easier to see things if the first drop-down menu option, and the header for its inline help, were the same words.

For visuals, here's the dropdown exposed:

And here's the help:
