mini mx box settings

hi,

newbie, so forgive question if obvious….

using krypton on mini mx box which is turned off at night. when going to kodi it boots with error message that python image library isn’t supported. then works fine.

a. how do i remove the offending library?

b. how do i set up krypton so it remembers my previous settings and doesn’t need to ‘migrate’ add-ons every time it’s started?
