New listings not winning buy box?

I’ve sold on Amazon off and on for the past couple of years and recently created some new FBM listings. None of them are winning the buy box even though I am brand registered.

After I launched the listings I remembered 2 years ago I did a similar thing and out of the 10 listings I created, only one of them got the buy box but couldn’t figure out what the difference was (wasn’t price). I even shipped in a couple units for FBA and still didn’t get the buy box on the other 9 listings. Last time I wasn’t brand registered so thought that might have something to do with it.

My account health is perfect and there have never been any fulfillment issues. How can I get the buy box this time around?
