Unexpected hyperlink and caption having “h2” font, being added

Hello, I'm having these issues with this new RSS feed. 1. Posts include hyperlink tag that's not in the source post. 2. Caption having "h2" or "h3" size in my posts. 3. Looks like there's 2 or 3 <br> added between photo and caption in my post. It's not in the source post. 4. Photo seems to look smaller in my post, while it's full width in source post. Link to my post. Link to source post. Hope you can take a look and help me fix these. Thanks!
