Help with Titlebar Image and Header with Impreza Theme

Hi there,

I recently updated my Impreza theme (also using Visual Composer) and it made two changes that I can’t figure out how to fix.

The first is that in all my posts, the featured image in the titlebar no longer shows:
https://www.the-heart-center.com/ep-20-break-up-survival-skills-with-anita-stoudmire/
and it’s just a grey background, rather than the featured image. The pages still have the featured image, but not posts.

The second is that my category pages no longer have any header at all:
https://www.the-heart-center.com/category/podcast-episodes/
and generally looks terrible.

Unfortunately I am not paying for a license anymore so can’t post on their forum. Any help greatly appreciated.
