Hi everybody

I'm having issues with the bibliography and cited websites. I have linked Zotero to my Overleaf (the Literatur.bib)

Here is the setup:

% ------------------------------------------------------------------------
\usepackage[backend=biber, style=apa]{biblatex}
\DeclareLanguageMapping{ngerman}{ngerman-apa}

% translation
\DefineBibliographyStrings{ngerman}{
retrieved = {Abgerufen am},
from = {von},
nodate = {o.\,D.}
}

\addbibresource{Literatur.bib}
% ------------------------------------------------------------------------


For one website zotero uploads the following information in the Literature.bib file

@online{WhalesLikelyImpacted,
title = {Whales Likely Impacted by Great Pacific Garbage Patch},
url = {https://theoceancleanup.com/updates/whales-likely-impacted-by-great-pacific-garbage-patch/},
titleaddon = {The Ocean Cleanup},
urldate = {2025-09-30},
}

And the output from "\printbibliography[heading=bibintoc]" is for this website:

"Whales Likely Impacted by Great Pacific Garbage Patch [The Ocean Cleanup]. (o. D.).
Abgerufen am 30. September 2025 von https://theoceancleanup.com/updates/
whales-likely-impacted-by-great-pacific-garbage-patch/"

But that's not correct for a website, where the Author and Date is unknown. This is how this has to look like:

"Whales likely impacted by Great Pacific garbage patch. (o. D.). The Ocean Cleanup. Abgerufen am 1. Oktober 2025, von https://www.theoceancleanup.com/updates/whales-likely-impacted-by-great-pacific-garbage-patch/"

I tried already to work with different macros but they all don't seem to work.

Can someone help me with this issue?

I am thankful for every help!

Best
Leon
