Shape+text issue when saving to PDF

[HMS]

Hi everyone,
I have a problem when I'm trying to save a word document as PDF, when the document contains a shape with text on it. In word, everything looks alright, but when I convert and open the PDF, the text on the shape is almost entirely gone.



This is the document as it looks in Word:


And this is the resulted PDF:


I tried different settings, none worked, though if I change the font to a thinner one it may work, but I need to use this font. I know there's an immense number of settings that can influence this, I just can't find the ones that would make this thing work. Any idea how to get it working?
Thank you so much!

Never mind, I found a solution, if I right-click on the shape and got o format autoshape>layout and select "behind text" that makes the shape to be "ignored" by the text, and I can just place the shape under the subtitle, that works fine!
