Can't locate a style I created - Word 365

[KeithAul]

in the styles pane in word, i have all styles showing and in alphabetical order.

however one of the styles i created is not listed. Its called 'college info' . when I try to create a new style with the same name it says:

the style name already exists or is reserved for a buil-in style.

if the name already exists why wont it show up in the styles gallery or style pane? And how do I find it so I can modify it or delete this style?

Also, this style, college info, is not applied anywhere in the doc.

In the bottom of the style pane, you'll see 3 buttons. Please click on the third button (Manage Styles), it will open the Manage Styles Dialog box. Go to "Recommend" tab, and in the "Sort Order" drop down, select "Alphabetical". Now click on the style named "college info" and click on the button "show", and then click OK. Now you can see the style "college info" appears in the style pane.
