Union or Join doesn't allow selecting 3 or more input streams

When adding 3 or more input streams to union or Join, drop down menu for selecting correct input appear to be too small, so, I can't select anything. Previously, when adding new stream to Union, property window of Union would expand vertically and popup window with input stream selection would appear normal. Union or Join worked perfectly till Friday, after that, I can't add 3rd input stream. I've tried using different browsers, different PCs and clearing cache. Nothing worked for me.
What can be source of this issue?
Thanks.

    What browser are you using? Seems OK on Chrome (screenshot below). Note that ADF does not allow multiple streams for Joins. You'll have to add another subsequent join for more than 2 table joins.
