assigned Menu for an event is not correct with JEM Setting "Default Menu Itemid"

I have a  Problem with Joomla 5.4.0 and JEM 4.3.4 :
If I call the Detail event from Even Simple List 
the assigned Menu with the JEM Setting "Default Menu Itemid" is not assigned.
(set Default Menu ItemId=102)

Displayd URL : "http://127.0.0.2/component/jem/event/119:"

If I set "Search Engine Friendly URLs" (SEF) to no, the "Default Menu ItemId" works correctly,

Displayd URL : "http://127.0.0.2/?option=com_jem&view=event&id=119:hallensportfest&Itemid=102"

Should I permanently switch off the "SEF" or is this a issue in JEM.

Thankyou for your help. 

 

I patched override "\templates\shaper_helixultimate\html\com_jem\event\responsive\"
and now it works also for SEF URLs.

if ($params->get('access-view')) { /* This will show nothings otherwise - ??? */ ?>
<?php
$menu = $app->getMenu();
$menu->setActive(102) ;
$menuitem = $menu ->getActive();
?>
