Are you using a masonry bit that's too big for your plugs?
that hanger is prone to wobbliness, because it has a thin backing plate and all screws are in a single horizontal line. if the holes are a loose fit, you can pop a (headless) match in to snug the fit up
The plugs are in pretty tight. The last hole didn’t work out as it seems I’m drilling between bricks. Is there anything that will reliably work that I can fill the hole with to secure a new plug? Maybe I need to abandon the position and try and offset them.
