I answer to myself.I have unchecked "position" in the Indi menu and it continues to modify the length field in the LX200 hand panel.

This influences me at the beginning of the observation, when I turn everything on after synchronizing, when going to an object I get the error "[ERROR] Object below the minimum elevation limit." and I have to turn the LX200 off and on again for it to allow me to move the telescope from the planetarium or the Ekos, also the resolution speed of the board is very slow and imprecise.
In AR it gives a lot of aiming error and takes time to reach the requested precision.

Please, any ideas? What am I doing wrong?
