Disable Catch to address is not working

[pikos]

Hello,
I have created a domain without a template for a client and at first i had enabled "Catch to address" on his e-mail
Now i want to disable it, but every time i try to disable it, after the page reloads the old settings are still there.

Also, My mail server is Mdaemon

There is such issue in Plesk because MDaemon does not support option "Bounce"
