Slugs used instead of Titles

This was working fine, but now in all of the timelines it is displaying the slug instead of the title of the step.

For example:
initial-conversation instead of Initial Conversation

It looks like it’s even happening on your own website (https://process.cooltimeline.com/#watch-demo)
project-planning instead of Project Planning

Any ideas for a fix?

Thank you for this plugin!
