Contact information not autofilling in Safari
Macbook Pro (Retina display 13-inch, Early 2015 version)
Processor: 2.7 GHz Intel Core i5
Safari on my MacBook Pro is no longer autofilling my contact information. I do not have this issue on my iPhone or iPad and it is only my contact information that does not autofill. All my passwords and credit card information autofill when requested. The box for autofilling passwords and contact info is and has always been checked under Safari preferences. When I begin typing in the indicated box, a customize option box comes up, but nothing comes up when I click it. I am not sure what to do.
MacBook Pro with Retina display, macOS High Sierra (10.13.3), Safari Version 11.0.3
