If EasyAnalyticalRecords is off, the marc editor should not show the fields 773$9 and 773$0, as they're NOT in MARC21 standard. (Should also probably add a mention of those fields in the EasyanalyticalRecords setting description)
I am not sure we shoudl do this - we have the marc frameworks to define what is visible, if you add extra rules when to shwow what that will get confusing fast. $9 could also be used for another purpose by a library and then there would be no way to make it show.

The fields show up in the generic framework.
Also, the fields are hard-coded in the source, See frex. searchResults in C4/Search.pm
Sorry, but not seeing the problem. We have other custom Koha fields showing up in Default too. If you know what you do, you can always change them but they help you get started. As there is no competing use for $9 and $0 I think it's ok and can be hidden if needed.
