how to delete several podcast episides at once

Hello -- I use an iPod Nano 7G and Catalina 10.15.3. My ipod software is up to date.

Question. How do I delete five or ten podcast episodes at once?

Here's what happens: I want to delete, say, 5 episodes; I highlight them and click "remove." A box appears: "Do you want to delete this items?" (that's its own mis-spelling.) I click "delete from library" and all 5 disappear at once.

I do it again with another 5 or 10. It works. So far so good.

Next time, no soap. It will highlight and remove only one podcast at a time. What's up with that?

Thanks.
