Even after copying and pasting whats in the lib the LTspice gave "Can't find the model "BZX84C3V6L" "

I attached my standard.dio (had to rename so I could upload it), you could try replacing your standard.dio with this one? Make sure to backup your file beforehand though. If it works, copy over any diodes you are missing into the work working file
Also I have tested this under LTspice XVII using wine under Linux Mint 19.1
