How to set custom icon in "edit glances" screen

Hi everyone,

I recently created a glance/widget (named "Week Report" that shows a simple bar chart of your activity duration of the past 7 days. I created an icon for it (62x62) which correctly shows in the garmin instinct when viewing the glances. However, when I go into the "edit glances" screen (Hold Menu => Appearance => Glances), there's no icon showing. It just says "IQ" instead of showing a proper icon like
the original widgets have.
Can I change this, and if so, how?

Properly showing icon in the glance: (clock with an arrow around it)

In the "Edit Glances" screen, just showing "IQ"
