Domain access advanced blocks user 1 from editing all group nodes

Because of the project requirements, we needed to use OG and Domain Access at the same time, in able to add a feature of having selected private groups a (sub)domain of their own.

Due to this, the node access grants made by OG in the context of private groups are disregarded by Domain Access, making private groups accessible to non-members of the group.

After doing some research, I stumbled with Domain Access Advanced module. It does solved the problem, but another problem arose, ALL GROUP NODES CANNOT BE EDITED ANYMORE! Technically, node/*/edit is blocked to all users, even super user. The node access table (see attached) revealed contrary information and holds correct node grants, like admin can update Node A due to "Administer nodes" user permission. But "edit" tab in the node is inaccessible, so does the link.

What do you think is the problem? I've ran out of solution. I need your help.

Here's some threads I looked at for some help:
