Bug - Shape Stoke Size shown differently on watch

When I create a shape with Stroke Size 100 I can see that the shape sizes correctly in the Creator window. When I pull up the watch face on my phone, it still looks good. The problem shows up when I carry it over to my Android watch - the stroke size is greatly decreased (possibly down to 10). It looks like the Facer app on the watch doesn’t use the correct stroke size.

My computer is a MacBook Pro running Firefox 60.0.2
My phone is a Samsung Galaxy S8 running Android 8.0.0 and Facer 4.6.0_95365
My watch is a ZTE Quartz running Wear OS 2.12.0… and Facer 4.6.0_95366
