Confidence Interval in Prediction Profiler - grey area missing

The prediction profiler of a least squares fit with four continous factors shows for one of the responses in a specific range of the factors only the blue lines for the confidence intervalls, the grey area is missing. Might that indicate an issue of the model or what could be the reason?

I'm not sure what happened there and it's one of those things like when you take your car in for a repair of "that noise" and the noise isn't there when the mechanic is listening.  Please send our tech support folks a note and let then know what happened.  They may have more insight than I do.  support@jmp.com

It's hard to say without seeing your profiler.  In some cases you might have really good fit for certain variables and the error lines are just really tight on the model prediction line.  Are you able to share a screen shot of your profiler?

One other thing you can try is "stretching" your Y axis by using the grabber hand on the axis itself.  Hover over the Y axis until you see a hand that is pointing up or down - not sideways and then stretch your Y axis out so that you can potentially see the error bars.  You can do something similar by double clicking the Y axis and typing in the upper and lower values that will widen the view out for you.

Unfortunately I couldn't reproduce the effect. However I will attach a screen shot of my profiler.
