On my minecraft realm server has been loaded without my consent a pack of textures that I did not buy or download but corrupts my game

Just yesterday I uploaded a new world to my server since the previous one stopped serving with the update appeared a pack of Sonic textures that I remember seeing in store but that I didn't buy or download for any source... The fact is that even installing a texture pack from the store, Sonic's will overlap and make my world look horrible. Before the upgrade this had happened but I am getting tired of dealing with these problems.
