Garmin BLE cannot find an advertising device

My device was advertising in this way. But Garmin cannot find the advertising info. I have made a data field app based on https://forums.garmin.com/developer/connect-iq/b/news-announcements/posts/would-you-like-some-raspberry-pi-with-your-connect-iq this project. It can correctly find other BLE devices except this one. So is it a bug?
