Zotero import template bug

What I’m trying to do

I am using a Zotero import template from Danny Hatcher that I like very much. I would like to add a persistent notes section, where I Can add my own thoughts, and not have them disappear whenever I update the same reference from Zotero in the future.

Things I have tried

I have tried adding the following text to the template. When I import from Zotero for the first time, this works fine. However, if I add text to the persistent notes section, and try and re-import from Zotero, the new persistent note stays, but all of the notes imported from Zotero disappear.
Does anyone have advice on how I can fix this bug?
Here is the template:

Title: {{title}}
Tags: {{hashTags}}

Authors: {{authors}}
Zotero link: {{pdfZoteroLink}}

Persistent Notes

{% persist “notes” %}{% if isFirstImport %}
Write notes here!
{% endif %}
{% endpersist %}

In-text annotations

{%-
