When using "Copy Settings" and "Paste Settings" in Lightroom Mobile 4.3.1 for iPad, "Paste Settings" deletes all healing brushes in the image that I paste to, even if no "Tools" are selected. I tested with selecting ONLY "Sharpening" from "Details" and it still deletes healing brushes. It does not delete gradients.
This issue does not occur in Lightroom for Windows, only on iOS.
