Bolding issue with Calibri Light when downloading to PDF

Hello, I am creating a newsletter for our team using adobe express and hit a very frustrating bug yesterday. When viewing the newsletter in express, everything looks perfect. I go to export it and download as PDF it bolds like this. I am using the Calibri Light and Calibri Bold for this newsletter.

I have only one word I want bolded, and then it bolds the rest of the sentence in that text box.

Boldeded is the only word I wanted bold, but it bolded the entire sentence. It did not do this when dowloading to PNG or JPEG, but I needed a PDF because of a hyperlink.

I was able to create a work around by creating a seperate text box for the rest of the sentence that came after the bolded word. However, that is so frustrating and time consuming. Hoping this can be fixed before I have to work on the next quarter's newsletter.
