Create Inbound email

Hello Everyone ,
i am facing this difficulty for a very long time now and i couldn’t find a solution till now.
As the topic says it is about creating inbound emails.
I think i did everything correct but at the level of selecting a trash folder i have difficulties.
The list of trash folders is empty so i can’t select a trash folder.

As you can see on the pic , the list is empty.
Did someone face a similar problem and has a soltion for me?
That will be very nice cause i have been looking for a solution for this for a long time
