When you transfer ownership of an application using these instructions, there isn't any mention of what the "Show all Applications" checkbox means.
I'm relatively sure that "Show all Applications" means show both applicants with applications (default) AND applicants without applications.
This can very easily lead to confusion as transferring applications to users without applications is a likely use case.
I recommend one or more of the following options:
1) Change the help article to mention the checkbox option and describe what it means (as the current label is unclear)
2) Change the default value of the checkbox to "Show all Applicants"
3) Improve the label to be more clear (ex: "Include applicants without applications")
4) Remove the checkbox option (as there's a search box/sorting already) and show all applicants
