How to disable header in Slideshow CK

Hi,
I'm uisng slideshow CK for a production site already (SLIDESHOW CK - version : 2.3.9)
During creation of a new site, I installed SLIDESHOW CK version : 2.3.12 and see an ugly black header line on top of the slides.
In source code, this is defined as a card-header
<h5 class="card-header ">some title</h5>

Question is now, how to get rid of this ugly black header bar ?
Thanks in advance, Alf

Hi
Please give me the url of the page so that I can check what would be wrong

Hi CEd,
the URL's are:
without black header bar: wimbauer-landtechnik.de/
with black header bar: eurotrac.de/hoflader/w13

The goal is to avoid the black title/header bar on site eurotrac.de
Besides of this, I'm afraid to face the same issue after SW - update of Slideshow CK on the other site wimbauer-landtechnik.de
Thank you in advance, Alf

Ok I see, this is the module title, its style is controlled by your template
you can disable the title in the module options

this is totally not depending on Slideshow CK

I'm wondering whether I can disable the title bar at all (not just modify it's style)
I've checked the options of the slideshow CK module already, but did not see an option like "title bar on/off"
Did I miss something here ?
Thanks in advance, Alf

this is a native joomla option, in every module you have the option "show title" ON/OFF
