Biblatex Types @incollection and @standard not recognized

I’m trying to format my bibliography, however I’m running into the issue that the Bibtex/Biblatex types @incollection (for book chapters) and @standard are not recognized. Instead, it treats them as generic types and falls back to the else clause in the CSL file.

Can someone give me a hint how to solve this?

This seems to be an open and relevant issue for exactly the issue with @incollection: BibLaTeX `@collection`/`@incollection` mapped to Hayagriva and CSL types incorrectly · Issue #437 · typst/hayagriva · GitHub (Typst uses hayagriva directly.)

Instead of @incollection one could use @inbook at the moment, seems to be the workaround.

There’s an open issue for @standard as well here: IEEE: Standards incorrect in bibliography · Issue #272 · typst/hayagriva · GitHub
