wrong link generated by mini module

Hi Guys,
the event link in mini module is wrong. See example:  www.psychoanalyse-muenchen.de/oeffentliche-veranstaltungen
go to the mini module there and click on the event of March 20th. it links to a different menu item of you r component (timeline view from another category called "zoom" with alias online-veranstaltungen) 
this is the generated link by your mini module:  www.psychoanalyse-muenchen.de/ online-veranstaltungen/oeffentliche-veranstaltungen/online-veranstaltung-muenchner-psychosentagung-neues-zu-ursachen-und-zur-behandlung-von-psychotischen-stoerungen?month=3&year=2021 
but I want the link to go to oeffentliche-veranstaltungen/online-veranstaltung-muenchner-psychosentagung-neues-zu-ursachen-und-zur-behandlung-von-psychotischen-stoerungen?month=3&year=2021 
what's wrong here?
thnks, martin
 

sorry the title is wrong it should be : wrong link generated by mini module

..if I disable the menu item "Online Veranstaltungen" then it works, but I need this menu item....and it is not a parent category!

For this, I will have to check the menu, category .... setup... So please submit a support ticket sending me super admin account of your site, tell me ID of the mini calendar module which you are using on this page

I will check to see what's wrong and get it corrected for you
