When you click on the category icon.
First enter Hope Cemetery, that will bring up all cemeteries named Hope, then Hull, and Hope Cemetery, Hull, Iowa will will be there as a choice.
Click on the cemetery name and it will be added to the profile.
Don't copy paste the cemetery name because it won't be formatted correctly.
After adding the category you have to go down to the bottom of the profile and add categorization as the reason for editing the profile, then do full save.
That should work, if it doesn't, perhaps someone else will have a better answer.
