Data Grid Bug - component duplicates as data is being edited/deleted in the builder

I am on the editor, editing data on an overlay screen that has a data grid of the table.

at start it had around 200 rows… after deleting 100 and editing another 20-30 app slowed down a lot. i closed the overlay screen to find out the data grid single component on that screen had been duplicated maybe 30 times or more.

seems not a bug, but something a bit risky, when copying and pasting from the data grid… if there is an update being made instead the app is pasting the previous component in the screen behind the overlay.
