JQUERY - BUG - Sliding Window Does NOT Appear

Please help me fixing this JQUERY issue. The code seems to be alright but
it must be something that I am missing.
Main Site: http://codeberg.com/demo/cnc/
The Jquery in issue resides here: http://codeberg.com/demo/cnc/js/cb2.js
Issue: Upon clicking over the buttion namely "Choose Your CNC Machine [+]"
, (Please Follow the Steps Below), Machines Disapper properly but Sliding
Window Does NOT Appear.
Issue Recreation:
Click on Any Machine Pictures on the top part of the webpage, EXCEPT for
the 2nd Last Machine (CNC JR Table Top) from the Right.

You will notice a sliding window poping under. You will also notice that
all the machine images get hidden.

You will also notice a Button to appear on the Top Right hand corner.

All is good here till this far.
Now, click on the "Choose Your CNC Machine [+]" button on the top right
hand corner.

It will lead you back to the Images of the Machines being visible now. But
the sliding window will remain visible. It is okay also

All is good here till this far.
However if I now click on the 2nd Last Machine (CNC JR Table Top) from the
right, the machine images disapper properly but

the content of the Sliding Window Does NOT Appear. This is supposed to
appear.
Expected Solution: A code fix or identification of error for me to display
the sliding window - #cb_container_jr-table-top (as per html source code).
