Details
If you see the red exclamation mark in the drawing view properties on the Parts List tab, you can right-mouse-click on the solid body and get more information. If it states that the fill style used in the part is not present in the draft and you do not want to use the fill style from the part, the red exclamation mark does not go away.
Solution
In order to get rid of the red exclamation mark saying that the fill style from the part is not present in the draft, you need to first deselect the option 'Derive fill style from part' and then force an update on the drawing view using CTRL + SHIFT + Update view.
