purple color

Hi all,
Just starting to use Helicon focus for macro. (running on mac, using adobe DNG converter)
I did some stacks (5 images) if mushrooms lately, they were little overexposed (like 1/3 stop) areas on the images,
which normally, for my sensor (Canon 6DII) is no problem.
I stacked the images, and then postprocessed the resulting DNG in Luminar. Inoticed when do an exposure correction
like -2/3 stop on the (white) areas of the resulting image I saw purple color areas coming up, like the masks that you
see helicon is using in its process.
Is this normal, (ansd will I have to underexpose images that I want to focus stack a little, to prevent this) or am I
doing something basic operations wrong ??
