Claim page image displays as thumbnail & can't add collection title

I just launched my first open edition on Manifold and am mostly happy with how it turned out.

However, I can’t figure out how to add a title to my claims page or why the svg displays as a thumbnail on the claims page and on Floor app but seems to display fine on OpenSea, Rarible, LooksRare, and Foundation, and when opened directly in a browser. Would love some help, as I’m worried people will visit the claim page and think the image itself is janky.
