2 rows 3 rows fluctuating in my 11 inch DUDU7 after 18.4 update

ok so I posted few days that I was getting 3 rows in 18.4 beta and then with stable I got 2 rows. Today I upgraded to 18.5 beta and now I am back to 3 rows. To my surprise when I connected my other phone which is running 18.4 stable right after this beta and I am back to 3 rows on that phone as well. Not sure what is going on with it. I love 3 rows and for now looks like 18.5 did some trick in my unit to get me back to 3 rows. Any one else having this issue?
