Focus keyphrase not found in url - Wordpress page

Focus keyphrase not found in url.

Need a wordpress developer for a 2 min job.

I need someone who knows wordpress to fix this error. I can’t get the Focus keyphrase to permanently show in the url, despite updating/saving many times. It shows the domain name with this on the end ‘ /1340-2/ ‘. I need a windows dev who can fix this in 2 mins, and save the page with the url ending I want.

The keyphrase which shows in ‘ slug ‘ within the screenshot I will send you, is the Focus keyphrase i want in url ending. If you know what you're doing it's less than a 2 min job. But i am not a dev so don't know. I don't want anything else changed. Thanks
