Hello! I tested it on my side like you described but don´t have this issue. Do you have the actual Version of Seblod 3.3.7. ? Which Joomla Version do you use? Is your "site form" tab of your content type filled with the fields?
Sorry, now i understand what you mean. Actually i haven´t seen this feature before in Joomla :-) I think it´s something to be added to the bug tracker, because the edit link is in fact leading to standard joomla content edit form.
