I have just installed a shelf with a wardrobe rail using plastic toggle drywall anchors (see https://www.mitre10.co.nz/shop/cobra-universal-anchor-assortment-for-plasterboard-or-solid-walls-pack-of-20/p/161310).
The anchors have slightly come away from the wall (5-10mm), but are holding strongly. There is no movement in the shelves while still holding weight (clothing, as in wardrobe storage).
What are the risks with this? Will this need to be removed and the anchors replaced to ensure they remain flush with the wall? If so, can the same drill holes be used for anchors with a larger diameter than those currently used, or will I need to start from scratch on this?
