What's wrong with these crusty skies

hi! i’m a newbie having some problems with conversion. if you know how to fix this i would really appreciate it!

When posting about Image Conversion Issues, please include the following information:

  1. Which version of Negative Lab Pro are you using? v3

  2. If using film scanner, please include: 1) scanner make/model, 2) software used for scanning, 3) settings used for scanning. plustek 8200i se, silverfast, i’m using the basic automated workflow with only dust and scratch removal.

  3. Please add the conversion you are having difficulty with, along with a short description of what you are seeing wrong with it. basically ugly and wrong color skies that are weirdly bright and yellow. happens in a lot of images that have a bright sky. i’ve tried cropping in various ways, including and excluding film border and various elements, roll analysis and no roll analysis but nothing has worked well so far.
