RTL and AUTO mode not working

Good Evening,

In a fairly new hexacopter build (it has 4 flights mostly in Stabilize and Loiter) running Arducopter 4.0.3, i tried today for first time RTL and AUTO.
(not my first build, not my first time using AUto and Rtl but first time with this craft
and arducopter 4.0.3)

While in complete flight having more that 12sat and always 3dfix i came across two problems

  1. Switching to RTL simply stops the copter in place, hovering, in a stable altitude
    and never returns to Land. ( parameters are set up for landing). On this flight tried two times. In the previous flight tried with smart-rtl same response.

  2. Switching to Auto during Loiter flight completes only the first waypoint.
    In this specific log it had reach wp1,then stops and loiter indefinitely above wp1.( until i changed to Loiter mode)
    I had waypoint radius 1m and i also tried Delay time 1 sec and 0 sec (didn’t changed anything). In previous flight i setted up take off command first and then the same 4 wps. It again executed only the take off command that time.

At the following link(we transfer) is the log .bin from the flight

Please any suggestions are welcomed,
Thank you in advance.
