Autorange Y-Axis don't work as expected [Solved]

[V.V.V.]

Hello,

Autorange Y-Axis don't work as expected (nor "Both Axes" or with "Range Axe").

I have a gpx track with points with Elevation between 698m to 845m.

RouteConverter 2.18.5
   

Example of expected Chart:
   

I've been watching this for several versions.
¿have I do any change in RouteConverter parameters? ¿Does not work this function with gpx tracks?

I attached the expected chart and the track get from
