Photo luminescent ring issue - Trijicon HD XR Night Sight Set

I’ve had their HD sights in orange on my G41 for awhile and absolutely LOVE them. The tritium illumination is great, and the Orange photo luminescent paint on the front glows nice and bright after only 30 seconds of charging in bright light. However, I got the HD XR version for my P365 and the orange ring will NOT glow after several minutes of charging in very bright light. Even in total darkness it’s impossible to see the photo luminescent orange ring, only the tritium is illuminated, which sucks because half the point of this design is the bright ring on the front post. I mean, they still have tritium, but it’s substandard if half the thing isn’t right.
