Old bug in newest build? - Accented characters showing as HTML CODE in title of published Storyline 360 course

I have the latest build of Storyline 360 (3.43.22859.0) installed and I've been recently experiencing a strange bug that my colleagues (working with older Storyline 360 builds) don't seem to have...

This seems to be a new issue for me as previous published courses didn't display this behaviour. The courses are always published in French.

Before publishing, I checked the Player button to be sure everything was all right. All the accents were displayed properly (Picture 3). I had previously published for Web and for Review 360 and the problem wasn't present. 

However, when I was finally ready to publish to our LMS, the accents were displayed as HTML code in the title and the top part of the Menu. (Picture 1)

I copied the file to our shared server. My colleague opened it and this is what he saw in the Player settings. (Picture 2) - He corrected it and published it again without issue. I also had another colleague take a look and they had the same problem with my file. 

Yet, when I open the Player settings, I still see it like this. (Picture 3)

Any help/tip would be greatly appreciated!

Thanks
