Entry in .bib file is suppressed

[alwi]

Again I need your help. Here is an excerpt from a bib file.

@article{Dörfel_et_al_2002,
	title = {Die {Geschichte} der {Mykologie} des 20. {Jahrhunderts} in {Sachsen}-{Anhalt}.-{Boletus} 25, 1-157},
	number = {25},
	journal = {Boletus},
	author = {Dörfelt, H. and Richter, U. and Saupe, G. and Scholz, Ü.},
	year = {2000},
	pages = {1--157},
}

The result is listed in the bibliography and in the text, the year is suppressed:

Does typst require a defined order for the entries?

Can you share which citation/bibliography style you are using. I tested your snipped with a few styles and all of them show the year correctly.
