Removing an entry from Recent Imports takes away the history record for that
file. It does not delete the contacts or companies the import created, and it
does not undo merges into records that already existed.
The old confirmation just asked “Are you sure you want to delete this import?”,
which read like an undo. Anyone who imported the wrong file could reasonably
click it, confirm, and believe the records were gone. They weren’t.
What changed
The confirmation now states the scope:
Remove this import from your history? The contacts imported by this file will
not be deleted.
Both the contact-import and company-import screens show it, each naming the
records it actually created.
Undoing an import — actually removing the records it added — is a separate
capability we’re tracking on its own.
