Deleting Pages custom field, orphaned data

[opentype]

I just removed a Pages database field (type: URL) but the content remained visible. The field is removed from the form and the field list, so I can’t actually change the content anymore, but when the record is viewed, the old content is still there. I replicated it with a test database on another installation and I made sure it’s not a caching issue. The data column is indeed still in the table and can be called from the template, even though the entire field was supposedly deleted. 

Is this data now cleared later or is this a bug? Either way, something is not right there.
