Email Scheduled folder clearing options Error

I would like to delete emails older than 60 days in particular folder. Reproduction Path: 1. Go to Virtualmin 2. Go to DOMAIN 3. Go to Edit Users 4. Select the user and "Login to Usermin" 5. Go to "Manage Folders" 6. Create new Folder 7. Select Auto-Clearing button

8. Setup autoclearing (attachment: autoclearing.png) Folder to clear FOLDER_NAME Automatically delete messages? Yes
   Deletion criteria:
   • Messages older than 60 days

- [x] Delete messages with invalid date Action when messages to delete are found: Delete matching messages

When I want to enable "Scheduled folder clearing options" for Mailbox folder in Usermin settings I get error:

"An error was detected in the new Cron configuration : 57 * * * * /home/DOMAIN/homes/USER/.usermin/mailbox/auto.pl"

But what worries me is after that "Manage Folders" web looks like in attachment (ManageFolders.png)
