I was just about to post another example of this. In addition, I find in the netlist generic devices NPN, PNP and D, which were in the .ASC but have been replaced by real devices, BC547B, BC557B and 1N4148.

Since several weeks the "SPICE Error Log" file contains these lines even when these transistors are not used:

Warning: Multiple definitions of model "2scr375p" Type: BJT
Warning: Multiple definitions of model "bc857b" Type: BJT
Warning: Multiple definitions of model "bc847c" Type: BJT
Warning: Multiple definitions of model "bc847b" Type: BJT

The multiple definitions are in c:\Users\...\AppData\Local\LTspice\lib\cmp\standard.bjt

E.g. 
2SCR375P: Rohm, twice with identical parameters
BC847C: Duplicate from Rohm with wrong parameters, e.g. IKF=1.3 Vceo=32, Icrating=200m, base collector and base emitter capacities interchanged ¡­

I am using LTspice version 17.1.9 and did never edit this model parameter file.

Does anyone know how the duplicates got in and how to avoid duplicates in the future?
