Isn't that obvious?
You are using Godaddy nameservers. So, ofcourse Godaddy will list your domain as "For Sale".
Others will show it as 'Taken' or such sort. Why they should show your domain is for 'for sale' in their marketplace when they have nothing to gain?
And obviously some will show 'for sale' in their marketplace. Which then again have collaboration with Godaddy.
