I've used the profiler before to optimize across several responses by saving desirability functions for trimmed down models and then bringing them into the profiler. The last few times I've done this though, it keeps only displaying settings & when I check the formula it actually does not show the inputs/factors in it, just a matrix with upper/lower limits for the responses (even though I've taken them out). I've tried labeling factors as role "x" but this does not help. Not sure what I am doing wrong? This has worked for me in the past.
