I asked the question to MedHelp. It turns out the message at the top is indeed related. Their reply contains:
the pain tracker is one of the trackers that we have not been able to design with our new design, and the old design isn't compatible with some recent updates.
We do hope to be able to redesign the pain tracker, but don't have a set time line on this being finished.
So sorry we don't have better news for you about getting the pain tracker working- but please let us know if you have any other questions.

Initially, I see a message at the top:
Pain Tracker new design is not available.
Is this message related to the issue?
