Email Initial Sync Count ignored?

I have connected my email account. I set
Email Sync Option = ALL
Initial Sync Count = 250

So far it has ingested 11,312 of my old emails and it’s still running…

Why is Initial Sync Count not respected?
Can I cancel the sync process? Because it is still ingesting emails from 7 years ago and may end uo with hundreds of thousands that I don’t need.
