Too many Fusions in my add on

Hi. I am very new to Kodi. I have downloaded a few things on kodi using step by step instructions. Now i have too many ‘fusions’ in my add on. How do I get rid of them safely? I don’t understand the technicalities. However when i followed the steps each time i was told to name it fusion which i did. Now i have 3 seperate fusions. Lol.
