In other words, if you enter, say, the letter "R", it the search bar will now contain "RR". Also, sometimes hitting the left arrow key in the search bar will delete both letters that were entered. Backspace does the same. The only way to get rid of the double letters is to try to navigate to the second letter and hit the delete key. Sometimes even that solution is inconsistent. This was tested on Ubuntu MATE 16.04 Beta 1.
