scaling patterns is breaking image in photoshop

I'm trying to add patterns to a couple of colors on a graph to make it accessible and I was able to add and scale a pattern to one color, but after adding the second pattern as soon as I start trying to scale the pattern it seems to break the image and replace large sections of it with transparency both when I have the scaling dialog open and after clicking ok. The first screenshot is with the pattern at 100%, the second is as soon as I try to scale the second pattern(the one in the purple, the one in the green scaled like normal). Any ideas of what is going on and how to scale the pattern in the purple?
