Home arrow ? help needed please!

just finished new quad build with gps in beta (latest) it will not give me the home arrow or home distance all i get is a small horizontal line,
Been building for years & never seen this tried everything i know anyone have a idea ?

To get the home arrow you have to wait for the GPS to get a lock and show at least 4 sats within Betaflight ( you can show sat count on the OSD ).

With 4 sats the arrow will only show up after you arm
