Hey Steve,
I've tried import this feed
https://hightimes.com/feed/ in my locally, it actually this is what this feed provided that content itself, you can try copy this link then paste into your browser.

view-source:

For some reason who create this RSS feed, they already put the full content into this <content:encoded> tag, you can refer on my attached screenshot below so you can better understand why it import those content into Easyblog.
How this import feed work is, it will import this <content:encoded> content into Easyblog.
Unfortunately that was not possible to adjust this since this RSS feed is not created by us.
