If you are clicking on the arrow at the top of the page, it is taking you BACK to where you were before you clicked on the flowers, and that is why they are green again. If you click on the categories on the left column, they will stay orange as you are not going BACK. Make sense? ;)
It doesn't matter how I navigate back and forth it goes back to green it seems to take a few minutes before it really registers orange. I tried using the tabs such as personal to get back but it still doesn't register. Seems like I have to go to another topic(tab) and come back before seeing a change.
The flowers never work for me. Doesn't matter what I do. So I give up. Hopefully, everyone gets the ones I send!
If you go back with the little arrow in the top links to the previous page. the flower goes back to previous too. So it will not be orange but green again. here's a flower for you now
