Cattleya Orchid Leaf Spotting

I just recently purchased two RLC Cattleya Orchids. When I brought them home, I noticed the media was degraded. So, I repotted them in a bark special combination orchid media. Within two days, these Dark Puple (almost black) spots formed on a few of the leaves. Further, they are soft to the touch and spreading quickly. I believe it is a fungal/bacterial infection, but I am not sure. Does anyone know what this is? what is causing these spots? and how can I treat them? I included a few images for reference. Thank you!

Its a bruise, use a sterile knife point or razor blade & cut the surface of the black area & apply a fungicide powder or cinnamon powder & keep the area dry. Should stop it.
