Getdist: parameter name not found: f_ede

I'm trying plot the contours for the MCMC results of my model generated by cobaya sampler through classy and getdist is failing to find two of my model parameters. I defined them in the .yaml file as follows:

latex: f_\mathrm{ede}
latex: z_\mathrm{ede}

I also checked my chain files and I found both parameters listed with the same names and their corresponding values. I'm loading my sample using:

settings = {'ignore_rows' : 0.3, 'smooth_scale_1D' : 0.3, 'smooth_scale_2D' : 0.4}

#load samples from the chain folders
samples = loadMCSamples('/directory/to/chains', settings=settings)

One thing to note is that Getdist generates the plots and it works well without any errors if I got rid of the 'ignore_rows' option which I use to remove the burn-in. The model has more parameters that were implemented in CLASS and getdist doesn't seem to have a problem with any other parameters. Any idea on what might be going on here?
