Why is "Fenix E" NOT displayed in the search when you check the "Built-In Gps" box ?

I go to Smartwatches -> All Smartwatches, checked Fenix.

• I see several Fenix models, including "fēnix® E – 47 mm". (https://www.garmin.com/en-GB/c/wearables-smartwatches/?series=BRAND473)

I check the "Built-In Gps" box.

• "fēnix® E – 47 mm" disappears from the list. (https://www.garmin.com/en-GB/c/wearables-smartwatches/?FILTER_FEATURE_BUILTINGPS=true&series=BRAND473&currentPage=1)

HOWEVER, when I open the model page and go to the specs section, it says it does have GPS.

Anybody knows the explanation for this ?

What am I missing ?
