How do I flip Chroma HDK Stripes 90 degrees in Chroma studio?

Hi,

I want to flip my HDK Chroma light stripes from horizontal to vertical by 90 degrees, but when I go to move option I cannot click the rotate button (its grey). Is there any solution? Thanks for advice.

edit: Solved, App is little bugged and you have to fines the mouse movement to flip button appear and click it.
