1. Add a few records - as you like

1. Then on the table, try sorting and then click on the Edit button and change and save some value

1. Try table sorting again

Expected Results

It is expected that the sorting has happened, and although the classification has changed, no new items will be added to the table.

Actual Results

As can be seen in the following video, the same behavior was noticed when we were conducting some tests in our instance, which is the fact that if you change the table dynamically and then retry the sorting, you will see an initial row reappear.

This can be noticed in the following video:

Workaround

As a workaround, the extra rows that reappear need to be manually deleted.
