No way to fill these gaps? :-(

[smartavionics]

Have you tried using thinner wall lines?

[Predator75]

Yes smartavionics, thanks, if I print with a thinner line or I print only 3 walls count the sharp angles are not created.
But why do not it fill them?

In the "Shell" category right under "Fill Gaps Between Walls", make sure that the "Filter Out Tiny Gaps" setting is not checked.

It's checked by default because for many of the smallest gaps, moving the nozzle there and trying to extrude won't have much of an effect since the delay between the extruder and the flow through the nozzle basically prevents any material from being extruded in that tiny amount of time that the nozzle is over the correct spot.
