Hi @aniruddha123 ,
Do you mean that the selected item in your Gallery could not be rendered well in your Display form or Edit form?
Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned.
Currently, the PowerApps has been upgraded to 3.19075.25, please consider made some changes to your app, then re-publish it again, then check if the issue is fixed.
In additon, please consider set the OnSelect property of the ">" icon (click it to navigate to your Display screen or Edit screen) within your Gallery to following:
Set(CurrentItem, ThisItem);
Navigate(DetailScreen, ScreenTransition.None)
then within your Display form or Edit form, set the Item property to following:
CurrentItem
please try above solution, check if the issue is solved.
If the issue still exists, please consider re-generate a new app based on your data source, then check if the issue is fixed.
Best regards,
