"""""""""""""There are settings to change the thickness of the blade at the root and tip, then another slider for the curve between those"""""""""""""""""""

These 2 values actually relate to each other mathematically in airfoil design. The changes have to be planned.

Changing the chord length from 1 station then back again right After it within just 3 stations will be a no no....

You can check your chord lengths. They usually taper from root to tip.

I think the trick is to choose a "ratio" as a percentage of lift coefficient, then stick to that as you change the thickness or chord length (Or Both)

Choosing this chactoristic allows you to pick and choose a change you want, but maintain the aerodynamics as you go...
