Dired+: diredp-dired-recent-dirs not working correctly

Question

Linux Mint 21

Emacs 27.1

package Dired+, Version: 2023.01.14

1. M-x diredp-dired-recent-dirs
2. Dired (buffer name): my-buffer

Here result:

As you can see the count of recent folders = 10.

OK. Now I go to folder temp

And open folder myfolder (press ENTER)

Now I again use this commands:

1. M-x diredp-dired-recent-dirs
2. Dired (buffer name): my-buffer

As you can see, nothing changed. In this list not exist folder myfolder. The count of recent folders are still = 10

P.S. In folder myfolder exist one file.

Answer 1

See the documentation:

A directory is recent if any of its files is recent.
