Storyline Preferences - resetting to default at every start up

Thanks Joe. I had a chance the other day to reach out to your colleague but they haven't gotten back to me. I have tried everything specified in the erratic behaviour link (https://www.articulate.com/support/article/Articulate-Storyline-360-How-to-Fix-Unexpected-or-Erratic-Behavior) but still, the colour swatch fails to save any custom colours.

Here's a screenshot with a new colour added. Yay.

2 custom colours. Wowwee! Crazy times!!

Hit OK. Save file. Close file. Close Storyline. Open Storyline. Open file. Click Shape Fill. Click More Fill Colours and see this...

This is not trivial. It's pathetic. At least allow us the opportunity to import colour swatches from other applications. Give us the ability to add, edit, and delete colours within the Custom Colour palette (when it works).
