Masking/Gradient Tools Broken

Ive tried with numerous photos in either the B&W or the Curves section to apply gradient filters and the constant default color is a fuschia. I cannot for the life of me figure out how to fix this. It works correctly on my iPhone 6 but not on the iPad. Need to update??

*UPDATE* i figured out that you could go into the settings menu of every mask and toggle to highlight the mask area. My problem is resolved! I would like to see something similar to LR where you could choose to see the applied mask area with a 2/3 finger touch register. That would be great!! I love this for editing, this is such a powerful app its almost too much to comprehend at once. Mastery of this is more akin to a higher education degree. But seriously KUDOS to the dev for developing an app that can literally do what LR can do minus a few features. Please keep updating!!
