Refer to the attached.
I think there were a couple of issues.
1. Looking at the OOTB content, there is always a type called Standard, which yours did not have. I added that... not sure if that really mattered, I think it was more the second issue:
2. Looking at the OOTB CSV files, the second column in the .csv matches the values in the first column... I.e., for elbows, etc... yours did not have that, so I added that in.
3. Your lookup file name was to a .txt, this should be .csv
