I'm creating a character for a Theros campaign and using Homebrew Feats for the Supernatural Gift features (specifically Heroic Destiny). 

The first feature, Defy Death, works fine. But the description on Hard to Kill doesn't show up in the main Feats list, only on the pop-out. Images below of character sheet and basic feat information. Am I missing something somewhere? Is there somewhere else I need to put the description to make it work? I had it in the Snippets box but that didn't seem to help so I deleted it from there.

The Snippets box is the place for it.

Like I said, I had it there, but it wasn't showing up. It was copied exactly as it's written in the description box.

Edit: I added it again and now it is showing up. I wonder if it was some kind of copy/paste issue?

Put it in the Snippet box for both the feat itself and for the action it provides. Re-save the action, then re-save the whole feat, then wait up to 20 minutes to make sure the server has updated. If you still cannot see the description, remove the feat, refresh the page, and then re-add the feat.

 It was probably a caching issue with the server not having caught up to the changes yet. It can take up to 20 minutes sometimes.
