Applied texture changes color on export

Hi there! I need help with this issue, please. I apply a white & black texture to a design using the transparency option. After masking, the texture looks white in the illustrator artboard, however, on export the texture on the picture is black. Furthermore, if I open the picture on the web it goes back to white, but on PC looks black. It's really confusing, I don't understand why it exports to black when I see it white on my artboard. Any help to make it stay white on export will be highly appreciated. Thanks!
