Hi @afew001,
I hope you are well today and thank you for your questions.
However, I have posted a new post today and the little brush/pencil icon is back on all of my posts!
I could confirm the issue on my test site that the custom CSS code added in the theme option is not working, therefore, notified the theme developer about this so that it will be fixed.
The issue will be fixed ASAP.
I have gotten an email stating that a update is available but when going into my WordPress it says that all themes are up to date.
You can update the theme on your site to the below latest version as described here https://support.shufflehound.com/updating-theme/

Best regards,
