Range selection

I tried the procedure to identify documents with keywords found in this thread: https://forum.literatureandlatte.com/t/finding-documents/33528/4

It worked perfectly.

When I return to the binder, I find that if I select a range of document that were left unhighlighted by this procedure and then apply a status and/or a label, the status and/or label is applied to the first item in the range only for any range equal to or bigger than 2.

I have long, nearly 100 item ranges, and several of them. Without being able to change a range I have to make 100s of individual changes.

What to do?
