Happy to help @Dimitris_Angelakis . So far, the problem is displaying correctly for me in both Chrome and Firefox. Have you been able to reproduce it yourselves, or have you only seen student reports? If it’s the latter, then my guess is that there may be a common browser extension that several students are using that is mangling the problem text. When I worked at edX, there were a couple times where some students’ auto-translation browser extension was disrupting CAPA problem rendering.
