Can you please compare the contents between following folders
/usr/lib/julia/JuliaPro-1.2.0-1/JuliaPro-Juno-1.2.0-1/julia_atom_1.2.0-1
$HOME/.julia_atom_1.2.0-1
They should be exactly the same, if they are not, then please copy the contents of /usr/lib/julia/JuliaPro-1.2.0-1/JuliaPro-Juno-1.2.0-1/julia_atom_1.2.0-1 onto $HOME/.julia_atom_1.2.0-1 , this should solve the issue.
Just a FYI:- You don’t need to install JuliaPro with root privileges, you can install JuliaPro as a non-admin user too.
