Hello,

Sorry i don't speak German...

But your issue seems related to module iC Event List (pro module).

Could you better open a new Pro Support Ticket for an advanced support (as maybe a bit of customization needed, as display difference is due to title lenght... and some improvements for this module planned in the future, so better to be in contact on Pro support )
pro.joomlic.com/en/support/individual-issues

Thank you!
Best regards,
Cyril
