Can I correct that or it is necessary to work on that?

Those migration settings are quite old and only apply to a few of our oldest customers. We're revamping the Autotune tool due to changes that Facebook has made recently and those migration settings will likely be removed in the process to avoid confusion.

There is nothing for you to do, or nothing you can even do, to adjust those settings right now.

I hope that helps, and sorry for the confusion. Of course, if you're having any functional issues, please don't hesitate to let us know and we'll gladly help investigate further.

Thanks,
Alex
