Why does a BASH script set the value from a previous version of the script?

I have a script using ImageMagick’s mogrify command. I re-wrote it to set the image quality to 80, but it still applies a quality of 75 (which was what was set in a previous version of the same script). Should I rename the script? I think “setbaseq” is nice, since it’s the value second-lowest value of 5 BASH scripts I’ve written.

Thank you for your considered responses.
