had no screenshot sorry (becuz it is Korean letter everywhere) but quite simple 1. i made a column for new (custom) data viewer (in another dummy project) and uploaded it to my dataviewer custom list. 2. i put the dataviewer for my original project 3. somehow there is new screen in original project. and it is same as the column in dummy project i had a few of custom dataviewer but only this one made another screen and it cannot be deleted (and this screen is not in the component list which is left in the thunkable screen) PS. i need the answer of this : [Suddenly thunkable initialize screen when re-open](http://community.thunkable.com/t/suddenly-thunkable-initialize-screen-when-re-open/862942) ---

okay. now the screen including this data viewer above, now when screen open it crash when live test and apk downloaded. if i click the component (of dataviewer list), then chrome browser goes white screen. Or if i clcik delete button of the component, then white screen and alert shows (for asking are you sure delete this). and if i press yes, then chrome stays white and no deleting at all. so i think i have to delete the whole screen and make new one. ---

Hi all, I do reopen this discussion as I just encounter the same issue. I’ve created a custom layout for data viewer in old interface and use it in DnD. The point is as soon as I apply the custom layout to a data viwer list in DnD screen then it pops out a new fantom screen which created navigation issue (navigtion block to not redirect to the declared screen) and background is disappearing in ios preview @Thunkable do you have a solution ? ---

Thanks, by the way, I discovered also that the custom data viewer is not displaying properly in ios preview. ---
