Random Texture Pack Appearing When I Activate a Texture Pack On My Realm

I have a custom texture pack that I made for me and my friends and I wanted to turn it on for my realm. I activated it and logged back on to find that my texture pack didn't activate it. I just ignored it and about 30 seconds later I realized that sounds like getting hurt, opening chests, and opening doors, were sound bytes from Fortnite. Potions were also from Fortnite. I have never downloaded this texture pack and it shows up as my texture pack in settings so I don't know where it came from. I disabled the texture pack and enabled a new one and it still makes Fortnite noises. I got the reference for my texture pack from the Minecraft website since it is a default edit. Please help, my ears are bleeding.
