Doesn't the orange Crown (as per the picture) mean you've completed?

I've got an orange crown on the course I've 100% completed including the course mastery challenge. 

On the other course where I'm 100% but haven't done the mastery, my crown is uncoloured.

Hi behshan,

The crown in the left-hand sidebar is not supposed to be colored in once you reach 100% mastery. This is just a static image, so it does not update as your mastery level changes.

I also wanted to share that we are updating the course page layout in the coming weeks, so this page will look much different. You can learn more about the changes here: https://support.khanacademy.org/hc/en-us/articles/17688542984461-Update-New-layout-for-Course-and-Unit-pages

I hope this helps!
