Links to documents open in Split View

When I right click (context) on a Binder document → Copy document link and insert or paste that link anywhere either inside Scrivener or in another app (Evernote, etc), the Scrivener document opens in split view, and I must View → Editor Layout → No Split.
There must be some option in my preferences file which causes this, but I can’t figure out which one.
thanks in advance for your time and help

Scrivener -> Preferences -> Behaviors -> Document Links.


thank you very much Katherine
