Cannot Change Theme Options

Hi,
I’m trying to make a couple of simple changes to the Sarraty theme for my website engineeringbizadvisors.com. I just want to change the phone number in the header settings and turn Enable Page Title and Enable Breadcrumb “off” in post and page settings.
I try to make these changes but the new phone number does not “stick” when I change it and the the on/off buttons are inoperable.
Please advise.
Thank you,
Steve
