If you're using the libinput driver, you need to use the libinput-specific
property - which is prefixed with 'libinput' instead of 'Evdev'. So I
suspect you changed "libinput Middle Emulation Enabled"

both the property and the option are documented in the driver's man page, 
man 4 libinput

bugs.freedesktop.org is our bugzilla, for next time.
