Some reason I can't select a prefix

[MrsPrime]

For some strange reason I cannot select a prefix when writing a thread. This means that I can't post any threads or even look for a developer for a project. Below is a gif of the issue. I would more than appreciate any feedback, i'm not sure if I'm doing something wrong or what.

Thanks in advance.

*Update: Another user suggested I try a different browser, so I now have it working. Still having issues with it working in Chrome but at least I have a temporary solution*
