Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

Whenever I try picking a language to start the problem it won't let me. Ive tried in a variety of browsers but none seem to let me pick a language. When I click on the arrow to pick languages, nothing drops down in the menu. Its not only in this problem but its in all the other 75 blind problems.
