Issue with Marlin and reprap display

I have the graphic 128x64 display and whenever I try to verify before uploading I keep getting this message saying "#error "Please select no more than one LCD controller option." What is this as I don't have more than one LCD selected I've been stuck on this now for hours trying to figure out what's causing it not to work.

from sketch\G26_Mesh_Validation_Tool.cpp:27:

SanityCheck.h:1485: error: #error "Please select no more than one LCD controller option."

#error "Please select no more than one LCD controller option."

SanityCheck.h:1705: error: #endif without #if

#endif // _SANITYCHECK_H_

exit status 1
#error "Please select no more than one LCD controller option."
