BuddyPress.org

Hello guys,
I need some help/assistance with a small issue.
On the first image youll see that the menu is on the left side, like a left side bar, but on the second one goes on the bottom. When you press My Account, View My Orders or Edit Address, the menu appears on the left side just like on the first screenshot, but as soon as you press one of the other links, the menu goes on the bottom and View Orders, Edit My Address are disappearing. Im not using buddypress template, it may be optimized for buddypress because everything else its working correctly apart from this. All pages are using the “Default Template”.

Can you help me a little bit with this, because it seems like I cannot figure it out how to fix it.

Thank you guys
