This is still an issue: Duplicate tags on sites view but not on the site detail itself
Hey @Stuurlui
Welcome to the MainWP Community.
I was unable to reproduce this issue.
Is the Manage Sites table being filtered somehow? If yes, can you please share a screenshot of filters?
And can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server (your-mainwp-dashboard.com/wp-admin/admin.php?page=ServerInformation), on the top right of the page.
Be sure to use the button like the one below; this button hides all your private information:
Pressing the button auto-copies the report to your clipboard then just paste it in a reply here.
