My dubia roaches

Sorry if I’m not doing this right but I have 3 dubia roaches colonies and I was cleaning one that has what looks like a white sack over the wings almost like the wings can’t grow it looks a female and has no male similarities. These a white sacks not clear. It does really look like the wings tried to grow and couldn’t . Has this happened to anyone else? I separated her from the group and looked at each colony. She was the only one.
