IPA [ɶ] Open front rounded vowel vs [œ] Open-mid front rounded vowel

Hello, Memrise. I’ve been learning this course: https://app.memrise.com/course/239573/learn-the-ipa-phonetic-alphabet/
However, these two IPA symbols look exactly the same under the current font used in the site:
[ɶ] Open front rounded vowel
[œ]Open-mid front rounded vowel
However, if you took them into a simple text editor, you’d see that they are different.

Is there any way that we could tweak the font to show the correct symbol?

Thanks for any advice you could give.
