Help fix a bug?

Hi! Recently, I downloaded a hairstyle created by Nightcrawler (it's called Impulse), and I decided to recolor it so the bun portion could be blonde and the hair on the scalp of the sims head could be brunette. The recoloring process worked fine, as I have recolored other cc hair before, but when I opened up my Sims 4 and used the hair on one of my sims, she had weird and slightly transparent white rectangles all over her body. I replaced the hair with another option just to make sure the problem was in fact the recolored hair, and, just as expected, the glitch didn't show up. I was wondering if maybe there is something wrong with the way I recolored the hair, or maybe even if the problem is unavoidable because the hair itself has an issue being recolored? I have linked the page where I downloaded the cc hair (from The Sims Resource) and an image of it in game (on a google site) below. Thank you for your time and help!
