This bug has been around for a while and I am bringing it up again in hopes that it is fixed. When changing the highlighting styles and using custom colors, those colors that you add to the color palette don't save once you apply the changes and close the window. What is odd is that this doesn't happen every time. Sometimes when I close and re-open the options, the colors have saved. Then I will close an open again and they will be gone.

We are able to reproduce this issue and we entered in QAT-6895 to investigate.
