Solved Slash not displayed in Breadcrum (Template T4 Blank BS5)

Dear community!

I am major-updating as many of you from Joomla 3 to 4 and from Kunena 5 to 6. And of course to Bootstrap 5. I have chosen Joomlart's T4 Blank BS5 template.

Now something strange has happened: The segments of the Kunena breadcrumb navigation display properly separated by slashes - as long as I use Joomla's default template Cassiopeia. They are produced by the "before" command and corresponding css:
 

But they are not displayed when I use T4 Blank BS5 template. The css is there but it is not called in the HTML code, the "before" command is missing:
 

Does anyone have an idea, why?

Thank you very much!

today i downloaded the latest version of t4-framework-for-joomla-4 and those templates and plugin and tested it locally with mapp server on my pc,
The strange thing is that T4 Template Blank - Default has that problem for me
but the t4_bs5_blank - Default is totally fine with the rendering

Funny! Okay I am goint play around with a clean install and both versions of the T4 Blank template. Just to see if I can reproduce it.

Hahaha, I have been so blind  ... Just turn this switch on and everything works fine:

 

glad you found it
that plugin is also enabled here
