Have you tried removing content from your library only to find it keeps re-appearing? Well don't worry that's normal XBMC/Kodi behaviour and it's simple enough to fix. All is explained here in this video.
If you like what I'm doing then a thank you and a like/follow on social media is always very much appreciated. However if you prefer to show your appreciation in the form of a donation that's extremely kind of you and really more than I could ask for but thank you VERY much :)
