Importing boltzmann two term into a plasma module

I am having issues importing boltzmann data into my model. After reading the following:
"The EEDF has to be imported to the plasma model as a spreadsheet consisting of three rows. The first row (x-data) has to be the electron energy (eV), while the second row (y-data) has to be the mean electron energy (eV)"
I thought it would make sense. I tried it and failed.
(I got that information from https://www.comsol.com/blogs/the-boltzmann-equation-two-term-approximation-interface/)
When I opened the argon boltzmann analysis tutorial to try to import it into the in-plane microwave plasma tutorial I never got the option for boltzmann under the EEDF section in the plasma interface. I used x as my expression for electron energy, and be.ebar for mean electron energy.
The blog also said "Meanwhile, the third row must contain the value for the distribution function (eV^(-3/2))" so I used f as my expression for that.
When I imported this there still was no option for boltzmann in the EEDF settings under the plasma node. Any advice on how to get that to show up?
