Instruments 'os_signpost' not working with OSSignposter

Hi,

I have been using the 'os_signpost' API along with the Instruments instrument "Points of interest", to track interesting intervals in my app. However, as it is deprecated (os_signpost(...) – Apple Developer Documentation) I tried replacing it with OSSignposter and the 'os_signpost' Instrument, as described here.

However, the image that they show for what it will look like:

does not at all match what I am getting:

Even though the same code yields this:

when I run it with the old os_signpost(...) API.

How can I use the new API and get the results I was previously getting with the old API?

EDIT: I should say my instrumentation of the code is identical to that of the link above, except I invoke my own code instead of their example 'let data = fetchData(from: request)' and 'processData(data)'.
