Open a new file in a new tab utilizing bookmarks

Hi, brand new to this promising plug-in, I've the following question:

I open up a new tab (tabe); go to one of my bookmarks (C-Space | b | select a bookmark | CR). Then CS states "CWD is now: ...". Next, I want to open a file out of this new CWD, BUT I only get the file list of the previously opened tab.

Even :e <tab><tab> doesn't give me a list of the new CWD. Instead :pwd tells me a different CWD than stated by CtrlSpace.

What am I missing here?
