No entries in Facet Invasive Arten

The thematic Search https://mvp.umwelt.info/de/suche?topics=Lebewesen%20%26%20Lebensr%C3%A4ume%5CInvasive%20Arten does not show any result, which is why the facet "Invasive Arten" does not show up as sub-topic of Lebensräume und Lebenswelten: while on the other hand having it's own main menu point.

I tracked down that the only UMTHES tag linked via https://gitlab.opencode.de/umwelt-info/metadaten/-/blob/main/src/dataset/tag.rs to INVASIVE_ARTEN is Schädlingsbekämpfung. This tag, however, is attached to some datasets, so I'm not sure atm why we don't seem to have results when using the topic search.
