[renamerOnUpdate] Filename Template group with hypen does not add hyphen

[skinnerback]

I have my default template configured to group date and studio with a hyphen. Per the notes it should include the hyphen if the date is included, and if the studio is included, but my log file is generating as $date $studio $performer without any hypens.

# you can specific group with {}. exemple: [$studio] {$date -} $title, the '-' will be removed if no date
...
use_default_template = True
# Default template, adjust as needed
default_template = "{$date -} {$studio -} $performer - $title - ($height $video_codec)"
