Médiéval textures

IHello man, I use Google translate for writing (I'm French). I'm coming to tell you that the "medieval textures" texture pack has a bug. Right in the middle of the viewfinder, there is a black square which totally ruins the experience of the pack and both of minecraft, unfortunately this pack I bought it and I do not know if there is a possibility of refund or so possibility to remove this black square, it would be really nice, thanking you.
put as ps4 version 1.95 because I do not see the xbox version I play on version 1.14
