CiviCRM 5.1.2, Drupal 7.59
We're attempting to add a price field option to an admin-only price field, and we're getting this error: "You must choose "Admin" visibility..." As you can see here (https://www.screencast.com/t/9n3VBhi9FTY ), I've clearly chosen admin. I also tried choosing public on the off chance the logic got reversed. (FWIW we've not been able to replicate this on the demo site; there are no error messages recorded in the log and no backtrace error was generated when I turned it on and tried again.) The client was previously on 4.6.x; has any logic around price sets changed substantively?
Thanks in advance.
