manage batch - after once new batch and add items  adding three patrons

I observed the following malfunction in 3.20:

In pataron card creator after choosing new batch:
By Add Item(s) I am offered a pop up window to search for patrons. In each row of all the patrons found for this search there is a button to add this patron to the (new) batch. After pressing this button the patron is really added to the new batch which now comprises just this one. If I want to add more patrons to the list and therefore continue  e.g. with another search and pressing add for further patrons to be included in the batch the chosen patrons are not added to the just created batch but instead new batches are crated and I end with several new batches each one with exactly one patron in it!


Apparently this is not so if  i chose to edit an existing batch. Add item(s) and adding several patrons results correctly in extending the current batch. This is also my bypass for the problem. I created a batch with the first patron in it, returned to manage batches, chose again the just created batch for editing an could complement it with the other wanted patrons.
