This is not how the system behaved before, so either there is a bug or if this is the new way it will start behaving, they’ll need to say it. I just had a similar experience that I had to do what you describe, but I’m sure I did not do that in the past (like last month) when I modified an csv. I just uploaded and redeployed. Now I have to delete, redeploy, upload, redeploy.
