Client-side metrics not showing on users profiles

Client-side metrics are not showing on user profiles. However, if I check the metric report, it shows activity.
Note: Metrics are not appearing on any client and at any time. It's not that they stopped appearing for new events. In fact, metrics that used to appear on a profile have stopped appearing. Now only server-side metrics are displayed. Can someone help me figure out what might be causing this?

Thank you.

(As example, this image corresponds to View Product Metric. On the users profile, there is not View Product metrics showing up.)
