Removing bibliography fields

Question

I'm using KOMA's scrartcl document to create a short paper where I've included some references.
I'm using
bibliographystyle{unsrt}
bibliography{references}

at the end to print the bibliography. Unfortunately, a field called tex.ids:... keeps appearing.
How can I remove that field for every entry?
I have tried using
usepackage[
   backend=biber,
   style=alphabetic,
]{biblatex}
addbibresource{references}

but I have errors about not being able to find the bibliography.
I'm using Overleaf.

The problem was that the tex.ids field wasn't a field per se but the text inside the notes.
It appears from the Zotero export (I import the bibliography into Overleaf from Zotero), but it doesn't appear in the Zotero app. After looking at the .bib file, I saw that it was in the note fields.
The solution I took first was to remove every non-useful field when setting the biblatex package options.
usepackage[backend=bibtex,%
    style=numeric,%
    sorting=none,%
    giveninits=true,%
    eprint=false,%
    url=false,doi=false,isbn=false]{biblatex}

Finally, I used the commands below in the preamble to clear the notes field at every item in the bibliography-
AtEveryBibitem{%
    clearfield{note}%
}
