Import in automation task keeps pulling table names

When my import item starts in my automation it keeps prompting asking if I want to cancel the background query which appears to be the import item pulling the list of tables again. I already have the table and query set, why would it need to do this? Will this interrupt the job when I schedule this?

Hi JP,
I tried to reproduce it but couldn't. Do you have a screenshot of the cancelling prompt? Is it Oracle?

It seems to have stopped doing it, so I'll assume it was just a fluke.
