remove hr tag

Hi Guys,
on detail page view there is a hr tag (grey line) under the description. How can I remove this line?
see here 2019.psychoanalyse-muenchen.de/veranstaltungen/event/483-vortrag-gruppenanalyse-intendierte-dynamische-gruppenpsychotherapie-der-gruppenanalytische-dialek
or see attachet pic:

Hi, in my template this line doesn't exist.
with firefox developer I looked into the css
and theres a link to:
theme.css line 309 in templates/jp-scene/css/theme.css
I don't know which JEM do you use
you can look into components/com_jem/views/event/tmpl/default.php at the start of Venue, it seems there it must be

you can try it with a template override, where you delete this <hr>

H Jojo12,
I remved the hr tag from default.php. tht was it thnx!
