Dexnav scan feature not working

When I try to use the scan feature, it only shows the option for Weedle. I have caught and registered about 620 pokemon already and am trying to shiny hunt Hawlucha (already registered in dex). Pls help.
Also, do shiny odds in friend safari stack with dexnav scan shiny odds?

Dexnav shows only a Weedle in the Friend Safari, it works fine in areas outside the friend safari.

oh ok thx
