Drilled wrong in aerated concrete - fill and try again?
Hello! I'm setting up an Elfa system, three tracks (not the hanging tracks but the older "bookshelf" system) in the hallway. In the system, we will have a hat shelf and several other shelves for hanging clothes as well as a shoe shelf. The first two went well, but when the last track was going up, the first top hole ended up too high, which would create an imbalance. So out with that screw and plug!
The problem now is that I want the hole exactly there but 5 mm lower. What's the simplest way to do this? It still needs to handle quite a bit of weight, even though there are more attachment points that will bear the weight.
The house is from -51 and the wall is made of lightweight concrete.
Can I repair the hole and drill a new one? Or should I expand the hole further down to a suitable place and then fill in with something (I've read about PL400? Never used it myself though) above the plug and let it harden? Is it better to use something sturdier than repair compound (And what would that be?) in lightweight concrete, or will it be impossible to drill into later?
The problem is that the hole is now too large and just slightly off to work with the rest of the tracks.
How do I solve this in the safest and easiest way?

I would expand the hole and glue the plug as you say. It will be crap when you try to drill so close to the sealed hole.
