Why is the profile page missing information, such as my personal stats?
Torn's API, which allows PDA to access information about your account, is often spurious and unreliable. This is exactly what has happened here - the API is returning inconsistent types, which causes issues for programs to read the data.
There is currently a bug report open here with the actual issue. Please do not bump the thread, it has been confirmed and will be checked out ASAP.
Yes, it is very possible for some updates to the PDA codebase to be made to fix the issue and get the profiles working again, however every update takes days to release and be checked (especially by Apple). Once Torn fixes the issue on their end, the fix will propagate immediately rather than having to wait for updates.
