Bug between Color 1.5 and REDCODE : clipping highlights the wrong way.

We encountered a problem during our tests for color grading with Apple Color 1.5.
I already posted about this bug about month ago, when Color 1.5 was released, but I had no answers, and as the bug prevents me from using this software, I'll ask the question again.
Here is the configuration we are using :
MacPro
AJA KONA3
REDROCKET + Installer v1.07 + RocketCineX 661
ATI RADEON HD 3870
Final Cut 7.0
Color 1.5
External Waveform Monitoring OmniTek
RED Final cut studio 3 installer : v20.00
Redcode quicktime v3.8.0
We have noticed that in Color, when we grade R3D files (transcoded with Final Cut 7 into Native, then in FCP in a REDCODE sequence), we have a problem with the signal on our external waveform monitoring (as well as on the internal Color's waveform).
When the Red metadatas are activated (RED menu in Primary), the signal clips at 95% in highlights. I tried to push the highlights really high, and the signal never goes over 95%, even if the frame is totally white.
When I disable the metadatas and grade the raw RedCode, the signal reacts normally and clips at 100%.
This actually happens even if I disable the inside Color clipper/and or force RGB in Color.
We tested with differents RED footages and it's always the same. I also tried to load other digital files, like F35 and D21, but there everything is normal. They clip at 100%.
As I never encountered this problem with the previous Color version, I wonder if it comes from the new sofware or from the new Red codecs, or if you have already heard of such a problem.
Thank you for any clarifications.

I'm sure you have tried this - but just to make sure - have you set the broadcast safe tab to off? Or - alternatively - have you tried it with the broadcast safe setting on and bumping the IRE up to max (110)?
Also - have you updated your Kona3 drivers to the new 6.5?
Also, what import profile are you using for the red footage (Log and Transfer>Little Gear icon middle top > RED FCP Log and Transfer Plugin.
I build a base grade in REDRUSHES and save the .RSX file at the root of the media that I will be importing, then select that one. Seems to bypass a bunch of small problems for me and get me grading in the right direction faster. Also have done pregrades on set with DPs using that method and then graded close to the imported footage. Works very well...
God luck - would love to hear how you solve this problem!
