I believe to have uncovered the source of the inconsistency. I have reproducibly generated the following outcomes:
Outcome 1: Gray-out display properties as desired:
Interaction Profiles must be “requested” in the JMP dialog via the drop-down for the Response as shown in the screenshot cursor:
--------------
Outcome 2: Gray-out display properties are not implemented, leading to inconsistency with respect to the terms included in the model:
Interaction Profiles are “requested” in the JMP dialog via the drop-down for the Prediction Profiler, a sub-item of the Response.
In the screenshot for Outcome 2, it the AC AD AE plots are not grayed out.
In fact, both modes of Interaction Profile panels can be displayed simultaneously.
In summary to have the gray-out/dashed line display consistently dependent on the inclusion of respective interaction terms in the model the Interaction Profile panel apparently must be activated from the Factor Profiling menu for the Response.
