Show Column type not working correctly

[Thilina]

Hi, So I wanted to create tabs in my form, I wanted to replicate what was done in the vehicle inspection sample app.
But in my case when I set the column as type SHOW all the columns below it disappear.
Plus they show up as heading and not tabs. Show type is also Page Header.

Before Show Column:

After Showw Column:

Any Help Would be Greatly Appreciated!
