Remove.groups - number of sequences removed from fasta table and count has difference of one sequence

Hi,
The remove.groups command removes different number of sequences from the fasta file and count table file

This is an example:

mothur > remove.groups(count=exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.count_table, fasta=exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.fasta, groups=exp44_b3m0_020423_-exp44_b1m3_060423r-exp44_b5m0_270323r-exp44_b1m2_290323r-exp44_b1m2_040423r)

Output File names:
exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.pick.count_table
exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.pick.fasta

mothur > summary.seqs(fasta=exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.pick.fasta, count=exp44_65samples.trim.contigs.subsample.unique.good.filter.unique.precluster.pick.count_table)

[ERROR]: Your count file contains 69791 unique sequences, but your fasta file contains 69790. File mismatch detected, quitting command.

I tried more than once and did the analysis from the beginning but the bug continues.
I tried doing summary.seqs without removing the sequences and it works.
So I believe the bug is in remove.groups

Best regards,
Debora
