Search in communities doesn't work

Search on main page doesn't work -  Bentley Communities 

If after inputting keywords it doesn't show suggested results then can't execute search as enter doesn't work. Search only works only if there is reply from suggestion box. Faulty design.

No issues with internet connection - https://www.speedtest.net/result/d/fac8df12-591d-4901-b0c0-b8a79ddc3193
