QTR-Quadtone RIP

I can't get linearised profiles to install for UT14 on Hahnemuhle Photo Rag Bright White.  I am getting the message "Invalid linearize curve -- not constantly increasing".   This is happening on both a warm and a cool profile.

The linearisation density values for both do constantly rise, however the paper white and 5% values are low and close, 0.02 and 0.04.  When the script runs in terminal, the line of numbers underneath the linearisation values has 100 twice at the end for both profiles.  The graphic curve representation ( lines of ****) also has lines (values) 244 and 255 near equal or equal.

Any ideas or advice?
