LefSe error: requesting groups not present in files, aborting

Dear mothur developers,

I faced the problem running the following command in mothur: lefse(shared=popov.insect_fruct.shared, design=popov.insect_fruct.design, inputdir=~/BioInf/Bats_16S/Statistics/processed_data)

The error:
You did not provide a class, using Food.
Comparing Insectivores-Fructivorous:
[ERROR]: requesting groups not present in files, aborting.
Segmentation fault (core dumped)

Can you please help with solving this issue?

Yours respectfully,

Can you post the output of running count.groups(shared=popov.insect_fruct.shared) and can you post the contents of popov.insect_fruct.design?
