You can change the distance that auto arrange uses to separate the objects. Right click on the Arrange tool.

Depends on what settings you have for the supports first layer expansion and if you use organic generally. Organic trunks for higher parts can grow out a fair bit and combined with the first layer expansion can take up even more room. Default first layer expansion is 3mm btw. I don't use organic a lot (snug mainly) so minimum of 6mm is what I have set and generally I dont see the warning. ymmv
