Issues with RED

My RED files don't seem to be affected by changes in Resolve to their metadata. When trying to adjust ISO/exposure for darker clips this is vexing.

Resolve Lite 9.1.6
iMac 27-inch, Mid 2011
Processor 3.4 GHz Intel Core i7
Memory 24 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6970M 2048 MB
Software OS X 10.8.4 (12E55)

see if the "general setting" is setup for clip/project/camera...
