Dear SMorrison_1111,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Thank you for the pictures provided. From your last picture, we can see the column is displaying as "PPA Title Old**(liked to item with edit menu)**". I would like to explain that this indicates this column is the default "Title" column. This is a system column created with list creation, just similar as "Created", "Modified", "Created by", "Modified by" columns. This type of system columns are not allowed to be deleted.
The original "Title" column can be renamed. It shows new name in the list and "All items" view. However, it still shows its original name "Title" in the list settings "column" area. That is why we couldn't find its current name "PPA Title Old" here. The related column should be "Title" in the list settings.
Your understanding and patience will be highly appreciated.
If there is any misunderstanding, please feel free to correct me.
Have a nice day!
Best regards,
