Profile tabs and arrangements

I hope someone can easily spot the schoolboy error I'm making. I'm trying to arrange tabs in a certain way but can't seem to manage it.

I'm trying to get all user details fields to appear inside a single tab.

I have 2 tabs set to right position:
-Personal details
-Subscriptions (CB Subs)
- Another tab called 'Contact info' of type cb core is also set to right. I can't unpublish it, but I cant choose to place my user fields inside this tab either (as it doesn't appear on the dropdown of available tabs) and changing it to type 'div' rather than 'tab' makes no difference. I am assuming this is the tab that appears as 'Profile', but can't be sure as no tab called 'profile' exists in my tab manager.

I'm stuck in a situation where if I publish the Personal details as a tab, it appears as a sub-tab of 'Profile', but if I set personal details to 'div' it appears above the subscriptions tab and the 'Profile' tab disappears completely.

What I want is two tabs, 'Profile' and 'Subscriptions' at the top. Inside the 'Profile' tab I'd like to place two 'tabs' rendered as divs with headers, 'Personal details' and 'Coaching details' (These just contain profile text fields). I don't want any second level of tabs.

How to do?? It must be simple, surely, but this 'Profile' tabs that appears and disappears as it pleases is annoying me. Years of using CB and I still haven't got a feel for the profile templating system.

Sorry, can´t see your attached images. Could you check it again, please?

In general, you should be able to assign fields to the CBcore tab "contact info". Its strange that you can´t select it, nor change the appearance style. Maybe an installation or upgrade bug ?

As far as you publish "tabs" on the same position:

- "tab" style arranges your tabs side-by-side, in a horizontal orientation.
- "div" style arranges the content ABOVE other tabs in the same position!

If I understand correctly you want to Nest tabs. You can enabled nested tabs within CB > Configuration > User Profiles. Please keep in mind it will not nest tabs provided by Plugins. This means it won't nest profilebook, profile gallery, cbsubs, etc..
