Hi wakywaky , thanks for sharing the site URL. I've taken a look at the dataobject of Buttonizer and it seems that there is a new tab defined on true somehow.
Could you try to toggle the new tab setting twice to 'enable' and then directly 'disable' it? Then publish your changes, this should reset the new tab functionality.
I think the dashboard somehow doesn't show the correct state. We'll look into that, thank you for noticing.
Let me know if this has worked!
