Only the last series of events is visible

Hello everybody,

I’m just adding a series of recurring events and something strange happens: When I enter a news series of events, all other disappear on the main event listing page and the event category page. Plus: At the category listing page the default image of the category is also shown at the location listings on the right column.

See https://gayguide.wien/events/ or https://gayguide.wien/events/kategorie/sauna-event/ for example, as you can seen the parties like shown in https://gayguide.wien/events/kategorie/party/ or other events from “sauna-event” are not shown.

Is there a bug?

Kind regards,
Herwig
