When importing into a contact list, you select from the right side index menu for the list and choose import.
The popup that then appears doesn't show the list you are importing to though, which would be helpful to the user as a confirmation they are in fact importing to the correct list.
See screenshot attached which shows this popup and somewhere on this popup, I expect at the top of the popup, the list name you are importing to should be included as a safe guard in case someone chose the wrong list to import.
Also just noticed that the list you are importing to also doesn't show on the mapping page. We should be including the list name at all steps in this process as safeguards and piece of mind to users knowing they are working in the right list after that initial click of the 'import' button.
