Cannot find my published widget in the store (for a "forerunner945-asia")

I published a widget (https://apps.garmin.com/en-US/apps/3c6110b1-6092-4af7-8803-2d63f0c9a13e). One of the devices it's compatible with is the Forerunner 945, which I own (purchased in Switzerland). When I search the Connect IQ store for this app, either via the Connect IQ phone app or via a logged-in web session, I see "No Results". I observed something unexpected in the search page URL:

https://apps.garmin.com/en-US/search?q=ruuvitag&device=&deviceLimit=forerunner945-asia&appType=&sort=&start=0&count=30

deviceLimit=forerunner945-asia

My app has no regional restrictions.

What makes my device a forerunner945-asia? And is it possible via the manifest to include this geographic variant?
