I have a realm and have a couple texture packs enabled but after the 1.13 update all texture packs stopped working and these 3 have been appearing, i tried disabling them but after when i exit and go back to the realm editing and texture packs it is activated again and i can not get rid of it. I searched my minecraft files for the textures but i couldn't find them anywhere and it seems as if this is on the realm servers. Some example pictures provided.
