Bismark soft clip --local_alignment True keeps L,value,value

[ioannagare]

Description of the bug

Hello community!
I have been trying to run the option --local_alignment as True to enable soft clipping and get this error:
In Bowtie 2 --local mode, the option '--score_min ' needs to be in the format <G,value,value>. Please consult "setting up functions" in the Bowtie 2 manual for further information.

When I look at the error folder the command.sh I see:
bismark
-1 file_1_val_1.fq.gz -2 file_2_val_2.fq.gz
--genome Genome_directory_runs
--bam
--bowtie2 --score_min L,0,-0.6 --local --maxins 1000 --multicore 4

The manual of bowtie2 says this for the case of local mode the --score_min needs to be changed:
--score-min | Sets a function governing the minimum alignment score needed for an alignment to be considered "valid" (i.e. good enough to report). This is a function of read length. For instance, specifying L,0,-0.6 sets the minimum-score function f to f(x) = 0 + -0.6 * x, where x is the read length. See also: setting function options. The default in --end-to-end mode is L,-0.6,-0.6 and the default in --local mode is G,20,8.
https://bowtie-bio.sourceforge.net/bowtie2/manual.shtml#setting-function-options

I suspect there might be an issue because in the browser when I create the options for local mode I am not able to change this to G,value,value and the default leaves the L,value,value which breaks the process.
Best,
Ioanna
