PDFs displayed in all caps in Zotero on Mac

Dear Zotero Support Team,

I have the issue that some pdfs (at least two of the same journal) are displayed in all caps when I open them in the Zotero Viewer which makes them very hard to read.
The PDFs are displayed correctly when I open them in Preview on the Mac.
Here's a link to one of the publications causing issues: https://bg.copernicus.org/articles/10/3445/2013/

Thank you in advance.
Kind regards

Could you post a screenshot of what you are seeing? What is your Zotero version? Do you see the issue in troubleshooting?
Here is what I see in Zotero 9.0.3

Here is what I see (also in Zotero version 9.0.3)

I am not sure what you mean by seeing the error in troubleshooting.

In troubleshooting mode it is displayed correctly

It would be helpful if you could identify which Zotero plugin is causing this and eventually report the problem to the plugin developer.
