Delete from server no longer in Advanced settings

I had the "delete from server" option set to never. I do not want emails I delete from my phone to be deleted from the server; I want them on my mac.

I have never had a problem until today. All emails I deleted from my phone today disappeared from the server.

I went thru setting to mail etc and into advanced Incoming server section. The option "Delete from Server" is no longer there.

Is anyone else having this issue.
