just checked out the logs you posted, i installed the same config.
contour is showing correctly for me on the enemy team
i do have the eye instead of the regular bulb
and for the autoaim i see this error in the python file
IOError: [Errno 13] Permission denied: './res_mods/1.14.1.3/scripts/client/gui/mods/mod_autoaim_indicator.json
so i expect most issues is related to permission issues, try to install the modpack with Admin rights and start the game with admin rights
hope that will helps out, else let us know.
