Remove the probe tip hybrid. According to https://www.tek.com/accessories/oscilloscope-probes/replacement-parts, the tip hybrid should should have a black tip and natural tail insulator color. Also, measure the cable length to ensure it is 1.5 meters.

Based on prior experience, there is a strong possibility someone has interchanged parts. The sum of the current components may no longer be as Tektronix originally shipped, creating this compensation problem.

You are a genius and I am an idiot. I got my replacement probe today and before reading your response figured out the same thing as the new probe compensates just fine. Turns out one of my p6156 probes has a black tip and I wanted it to have a blue tip. Swapped them over and it works just fine and dandy. Great call on your part and boy do I feel sheepish. Oh well, at least I now have 2 x p6137 probes.

Here are the probe tips. Offending probe in blue and new probe in black.


And here is my new comp from the old probe after switching for a black tip from a p6156.
