Custom Font

Hi All,

I have imported a Custom Font in Power BI Report through JSON file named as "Avenir Next LT Pro" and majority of the text has converted to "Avenir Next LT Pro" except for the radar chart 2.0.2 and the Gantt chart by MAQ software. I have noticed that the "Avenir Next LT Pro" font displayed in my report differs from the actual font. I am also unable to find the "Avenir Next LT Pro" font option in the dropdown for any text value even though it has been successfully imported through a JSON file.

Font that I got after uploading the JSON file:

Actual "Avenir Next LT Pro" font:

Code in the JSON file: (I have tried using two different codes)

I appreciate any suggestions or solutions you can provide.
Thank you!!
