Sample payment processor types are misaligned in the sample data
e.g. on dmaster.demo.civicrm.org it says Elavon is configured when it's supposed to be the dummy processor, and then when you edit it it says it's authorize.net, presumably because the id doesn't match up and it's just picking the first in the list.
I'm thinking this is a regression from some payment processor type rearranging but I think it's only affecting the sample data.
