Need help deleting a custom field

Ok, so I accidentally created a custom field called "Version" and attached it to my project "ManageMe."
http://managemebugs.myjetbrains.com/

First, I try to detach it.
I go to:
http://managemebugs.myjetbrains.com/youtrack/editProject/MM#project-tab=Fields
When I try to detach it, I get "Detach field 'Version' from project?"

I click OK and get "This field is not empty in 92 issues. After field deletion these values will be lost.
Do you want to continue?"

I click "Yes" and the custom field becomes grayed out, but is still there.


Then, I try to delete it.
I go to http://managemebugs.myjetbrains.com/youtrack/customFieldsConfiguration

I click "Delete" and see "All field instances will be removed and you won't be able undo this operation.Delete this field?"

I click "Yes" and there's no response.

What am I doing wrong?
Let me know if I can provide more info...
