I see 4 diaries in your diaries.
On your main page it will show only highlights and popular diaries that have accumulated a bunch of likes.
The name of it is based off of some weird shit GD does. Sometimes they make the URL simple, other times not so simple.
You an also edit the diary name from Highdog91 to something else in the settings of the diary.
Click on the diray in question.

Then look to the far right above the diary input pannel that shows lights, tent, seeds exct. there is a gray button "Settings"
Click it and select "Edit Diary" it will take you to the diary creation page when you first set it up.
Here you can edit the name from Highdog91 to something else.
If you are using any add blockers or anything disable them.
If it still does not work. can email GD to fix it but their turn around is slow and they almost never respond.
The URL for the diary will not change. but its name can.
