Unable to drop weapon in inventory

When I pressed ‘‘R’’ to favorite an item a waypoint symbol appeared in place of the star/box symbol. Now this item is permanently favorited in my inventory and I cannot sell/drop item.
Please help this is taking up a precious inventory slot!

Press R again and the favorite/trash icon should dissapear and you will be able to drop/sell that item

Things that I have tried which did not work!

  1. pressing R again to change from waypoint picture to star/box symbol.
  2. turning system off and back on (restarting game).
  3. Equipping item in and trying to drop it from there.
  4. dropping/selling/trading said item.

The problem literally fixed itself for me! 6 hours later after logging on I no longer have this item in my inventory!
