Gimme motifs not using -f (fraction) provided

[adeben1]

Describe the bug
Gimme motifs is not apparently using the -f value provided.

To Reproduce
I've run gimme motifs commnad providing input, background and genome in fasta format with the -s flag set to 0 as well as -f set to 0.5. Here is one example.
gimme motifs diff_peaks_down_MB.bed.fa down_MB_nocenteredx2_b_f0,5 -g ../../genome/Nfu_20150522.softmasked_genome.fa -b ../nucfree/allPeaks_MB.bed.fa -s 0 -f 0.5

Expected behavior
In the file params.txt, the fraction should indicate 0.5, however it appears the default 0.2.

Error logs
I copy the content of the file params.txt.

In addition, the .log file says it is using 0.2 as a fraction. From gimmemotifs.log:
2021-01-13 09:32:15,478 - gimme.config - DEBUG - fraction: 0.2
