Running Minera on RaspberryPi 2+.  Why is it that when I am setting up pools in Minera v.0.5, and save, the information is lost and/or the donation pool information get's put back on top as priority one,after saving and restarting?  I have tried deleting the donation pool, moving it to 2nd or 3rd priority, using time donation but with all these it reverts back to having the donation back to no. 1 priority and deleting the other pool information I saved.

How can I edit the json_config file?

thanks
