Scenes' hierarchy in assetbundles

Hello,

When loading scenes from asset bundles, the scenes’ hierarchy seems to be broken.
I mean, it knows the parenting but the siblings order is messed up, which is really annoying.

Is there any solution, an import/export option that I’ve missed or should I reset the hierarchy order on start by saving it in editor?

Ok, so it looks like this behaviour only appear in editor but works fine on the target (iOS).
