Hi there!
Thanks for reaching out.
The edit module flags are only visible on frontend if you are logged in with a super user account or any user who has the editing permission. In general these icons shouldn't be visible, so if visitors visit your site, they can not see this.
If you still want that, you can hide the frontend edit (pencil) icons / module edit badges in Helix Ultimate.
These appear only when you are logged in as a user with editing permissions.
Disable “Show Edit Icons” in Joomla Global Settings
This hides the edit icons for articles and modules.
Please do let me know if it helps!
Best regards,
