Wtf!! Buybox eligibility gone 3rd time in the last 30 days!

Third time in the last 30 days, I have lost buy box eligibility. First for less than a day, next for 4 days, and now again. WTF DUDE!No negative anything. Account health is healthy. Metrics are at 0% with 100 tracking rate. No need a to z claims. This is getting really annoying!!
