You are kind of misleading us with the information you are providing. You mentioned duplicating a Tab, but that’s not what you are showing us. What your screenshots show are a detail screen that’s different from the tab screen. You are most likely showing something below the Tab level screen. I can only assume that you are navigating through a collection on that Tab screen to the detail screen for one of those collection items. The action on the collection in the Tab is what needs to change. Like I said, change the action on the collection in the Tab to ‘Show New Screen’ and it will work the way you want.
Think of it this way. Imagine if you had 10 different ways to navigate to a detail screen for one of your techs, but you actually wanted it to be the same no matter how you navigated there. By using ‘Show Detail Screen’ as the action, you are navigating to the version of the detail screen that’s attached to the table. Now imagine if you had to change one small thing on that screen. Would you want to do it 10 times or just once. It’s a feature that you’ll be thankful for when that situation arises.
The solution is simple. Pick only one of your tabs, select the collection and in the collection configuration, change the action from ‘Show Detail Screen’ to ‘Show New Screen’.
I know it’s a hard concept to grasp, but I’ve covered it over and over in the forum. This is probably one of my better explanations:
