:D finally after months of annoyance, I got upset enough to enter the corsair files and found where each button is defined, tinkered around until I got Left click able to be remapped, imagine it would apply to other corsair models as well.
1. go to : "C:\Program Files (x86)\Corsair\Corsair Utility Engine\devices"
2. open the xml of your device in notepad, for me "profile_scimitar.xml"
3. near the bottom is the line
<protectedKeys size="dynamic">
<item>Mouse1</item>
</protectedKeys>
4. remove the line Mouse1 to create
<protectedKeys size="dynamic">
<item></item>
</protectedKeys>
