KStars on windows not saving data - by: nmac

I have been testing Kstars on Windows and found that when I try to save Primary and Guide scope aperture and focal lengths am I getting this error:

2017-04-17T13:58:54 Failed to save telescope information.

Any ideias to what is causing the issue?
Maybe because I am using simulators and those do not have the necessary fields on indi window? I haven't tested with real hardware yet.
Is there any config file where I can put this info? Astrometry is always giving a warning about this info.
