Inventory shows some of my listings as "featured offer" but when clicking through to the listing I am not the featured offer?

Hi All

I know that early in the year many sellers lost the buy box despite being the best price. This has not rectified itself for me & I have researched extensively & it appears that feedback, delivery times & even quantity in stock all play a part in winning the buy box, now referred to as featured offer.

I have several thousand listings where I am cheaper than the competition but they offer faster post & have more quantities. Today I noticed that when viewing my inventory the screen said "featured offer" but when looking at the listing my competition still has the buy box? Thoughts please...
