Just in case that any other user suffer from the same here is the solution!
From tyson:
It seems that the "model assist" viewport mode is not compatible with viewport instances. Disabling that mode and switching to regular shaded display returns the polygons to the view. Alternatively, you can add Mesh operators to your flow and disable "render-only" so tyFlow generates meshes in the viewport. Then model assist mode will display the geometry fine too.
