I would say it's a bit early for DOS. On your orange soap, it looks more like your orange powder/zest is the culprit. I make a soap with orange zest and it does the same thing. Do they smell off in any way? How old were your oils?
Your recipes look fine to me, similar to one of my recipes.
Bought oils week before making Orange Variant. I also made Activated Charcoal before orange variant and made Lavender and Rose clay soaps too but orange spot was not on Activated charcoal neither on rose clay they are appearing on orange soap and lavender soap
