Can you share an example feed URL? I'm still seeing authors in the ones I have saved.

Here is one : https://rss.arxiv.org/rss/cond-mat.mes-hall
Zotero seems to be reading what's between the "managingEditor" tags, whereas the list of authors is written by arXiv after a "dc:creator" tag.

Sure, here is an example of an entry from this feed:

< title>Dynamical tunneling across the separatrix

< summary>arXiv:2402.10219v1 Announce Type: new
Abstract: The strong enhancement of tunneling couplings typically observed in tunneling splittings in the quantum map is investigated. We show that the transition from instanton to noninstanton tunneling, which is known to occur in tunneling splittings in the space of the inverse Planck constant, takes place in a parameter space as well. By applying the absorbing perturbation technique, we find that the enhancement invoked as a result of local avoided crossings and that originating from globally spread interactions over many states should be distinguished and that the latter is responsible for the strong and persistent enhancement. We also provide evidence showing that the coupling across the separatrix in phase-space is crucial in explaining the behavior of tunneling splittings by performing the wave-function-based observation. In the light of these findings, we examine the validity of the resonance-assisted tunneling theory.

And the corresponding Zotero entry (without the creator field being populated):

It seems to be fixed indeed, everything works fine now. Before, the creator field only read "rss-help@arxiv.org" for all articles. Thank you for the fix !
