I’m trying to fix it on my own, but the questions (and my answers) are not visible in the question list even if I answered it already. Additional the date is always at "1 second" and if the question was answered it has the notice above -> "Your question was submitted and will be moderate". I can’t change this and couldn’t find the bug at this time. I’m using the german translation.
I think you have enable the Review Question feature in the Dashboard > Q&A Settings > General.
Firstly, you should uncheck the Question must be manually approved.

After saving settings, you can check again, if you still face there issue, you can send me username & password of your site (via private answer) for further checking.
