Google Slides: Text displaying wrong when exporting to PDF

[TLA]

Hi - Upon exporting to PDF in Google Slides, there is the chance that the text displays wrong. E.g. extra space is added between words, text goes onto another line. This issue persists in both the Google Chrome PDF viewer and Adobe Acrobat.

In the example below, the top image shows how it dispalys in Google Slides, and the bottom image shows how the exported PDF. In this example, the issue seems to be caused by changing the font weight to 'Black'. The font is Reddit Sans but it's done this with other fonts aswell.
