Only admin role can edit post after it is created

I am using Custompress to manage content types. I have a content type called "Stories". Iam also using Gravity forms and this plugin to allow the public to submit a story which creates a post under this CPT in draft status.

That is all well and good, but only admins can edit the posts, and draft posts can't even be viewed by anything other than admin levels. I'm trying to narrow down the cause since I have never encountered that behavior, but I am usually logged in as an admin, so I wouldn't notice.

I made sure that on the CPT screen in Custompress I checked all options for "editor" under capabilities. Any other suggestions for troubleshooting?
