why doesn't autofill work on some websites? Using 1Password for Mac 8.9.4

Hi Andrew. Thanks so much for responding to my question. I am on my iMac desktop using Safari 16.1. My typical way to access websites is to go to the 1Password app and click on the weblink from there. So for this example I click on the link (http://www.southwest.com). from my tagged list of saved websites and It brings up the Southwest site. I click on Log In. The User name and Password fields come up. When I click inside the username field or the password field, 1Password appears and gives me a choice of the 4 sign ons that I have saved for each of the family members who have their own accounts. When I click on any one of the four nothing happens. That is, it does not autofill.

A second method I have tried is to begin from the Safari browser extension. I will type in Southwest and it gives me the four options I mentioned above. I select one and click on Open and Fill in Search Options and I have the same problem. I have also tried moving to the upper right section of the Search Results where there is another Open and Fill option. Unfortunately, that doesn't work either. I end up having to do a Copy and Paste to fill in the user name and password.

The last option I have tried is to click on the 1Password icon at the top of the screen on the right side (not in Safari) (sorry, I can't remember what the name of the ribbon on the top of the screen is called) and click on Open Quick Access. I type in Southwest and have the same problem as previously mentioned.

I hope this gives you something to work with. If you need more information, please let me know.

Thanks again.

Bill
