Describe the defect

A clear and concise description of what the bug is.

To Reproduce

Steps to reproduce the behavior:

1. Go to staging.cms.va.gov (or a Tugboat)
2. Create a new Campaign Landing Page
3. Fill out the required fields in the sections Hero banner, Why this matters, What you can do, Stories, VA Benefits
4. Save the node
5. Edit the node and go to the Stories section and uncheck the "Enable this page segment" box without changing the content underneath
6. Attempt to save the node and get this error message. Notice that clicking on the link does nothing
7. Scroll down to the Stories segment and notice that there is no visual indicator that it is the fieldset that contains the error
8. Check the "Enable this page segment" box. Notice that there is a confusing error message that says image is required.
9. Click the Remove button next to Link teaser with image to remove the image
10. Uncheck the "Enable this page segment" box.
11. Save the node

Possible culprits / solution directions

• Featured stories field uses the legacy paragraph widget?
• Add form_alter to clear out sub fields on save when Enable this page segment box is unchecked?

AC / Expected behavior

• [ ] If a user unchecks the "Enable this page segment" box in the Stories section, they can save the node without further action

@FranECross The other ticket where clearing fields when segment is unchecked might fix this. Table this until that one is worked on and then test this one.
