Issue Description
While working on your project, you've begun noticing warning triangles appearing in the slab settings dialog box.
Solution
These yellow warning symbols highlight parts of the slab that have been changed independently, outside of this dialog box.
In the example below, the surface material and inclination angle have been manipulated separately for a single slab edge.
The yellow warning does not mean the slab is corrupt, they are simply aid to point out changes.
NOTE: If you modify one of the settings marked with a yellow triangle, a checkbox will appear at the bottom of the Slab settings dialog which will give you the option to Apply the changes to custom edges.
