how t keep the settings stay

i have been using kodi for a few days and i had tons of issues so i just reset it to factory, then i went and made some settings snd i took out the pictures snd the music etc. i kept the video and program and settings but then the next time i start kodi ll of them come back. i even took out in the video section the sports ball and phoenix but then they come back. so how do you keep what you change permanent? i have more questions but after i get this issue resolved
