Transparency turns grey from powerpoint to pdf
I use PowerPoint on a MacBook to create flyers. I then save them as pdf's in order to share them so that they won't be editable and so that the fonts that I have downloaded on my machine appear correctly on others'. This also happens when I use MS Word.
I usually use an image as a background and set a level of transparency so that it doesn't use too much ink or take too much attention from the text and other images. I also add "glow" with different levels of transparency so that the text and images pop against the background.
Since I've completed some updates, anything with any degree of a transparency setting turns grey in the pdf export. I'm attaching screen shots of when it has worked and when it hasn't.
I'm running Mac Mojave 10.14.1 and Microsoft 16.19.
Thank you so much in advance if you're able to help.
