Merged virus file abundance--is it really abundance or something else?

I used the most updated version of metaphlan4/databases to obtained --profile vsc for each of my samples. I then merged them into an abundance table. I summed up all the kSGB and uSGB for each sample and am getting different total values ranging from 1.99 to 52.3 for my samples. Typically when relative abundance tables are made in metaphlan, they sum to 100. Why am I getting a different number for each sample, if I am using a merge relative abundance table?

This is what my output looks like. The first row shows me summing up what is present in each column.

I used to make the above table.

Thank you for your help with answering this question!
