Is there any way the automation setting just builds up hospitals, schools and not messes up with education priorities?

I try to set high priorites for HT engineers and seniors but then next month the automation setting messes up my priorities and set other jobs' priorities high(which already have considerable unemployment)

click on the automation button. You can turn off the low level "help" for different parts of your economy. That should fix your issue.

I did turn that off but it hasn't worked

If I remember correctly there is a two week lock on new players changing some settings. You are clicking on the save changes buttons, right?

been a real month and did click save

I have the same problem, and I've already been playing this game for a short while.
