I’ve been led to believe this is a bug. Thanks Carl the Turtle bot.
I have a file for an author “Raymond St. Elmo”. My settings set to markdown links. I type [[Ra at which point the file is highlighted correctly to the Raymond St. Elmo file. I select it and get [Raymond St](Raymond%20St.%20Elmo.md). If I type in the entire name [[Raymond St. Elmo and hit enter to select the file, I get the same [Raymond St](Raymond%20St.%20Elmo.md). Thanks in advance for any info or work on resolving the issue. v0.9.5, Windows 10
