Somehow, I can see that there is a double Headline because of this beta feature, that means that instead of seeing "Uses", I see "UsesUses". For your attention.

Can you share a link to a page where this is happening?
Until now, it happened in 1 Wikipedia page and 3 talk pages (happened in here, here, here and here).
Thank you, I see the issue as well. I filed T274709 with some more details – the bug affects pages with the quote mark " in the title. I can see why it's happening and we should be able to fix it on Monday.
(Actually, today is a US holiday – Washington's Birthday – so we're not deploying any software changes except for emergencies, and I don't think this is severe enough considering that the reply tool is still a beta feature. It should be fixed tomorrow.)
