Evernote Web Clipper multiplies notes. How to solve the problem?

Question

Google Chrome

Problem with Evernote Web Clipper. I use the basic version, the place for notes is limited, and then something inadequate began. With standard page copying, instead of one note, whole series began to appear - 5 identical notes each, and some other left pages that I did not save at the moment, but they were open in the next window. That is, instead of one note I created, 12 pieces appeared in my account! Accordingly, half of all MB flew away at once! What to do? Who to contact? This have not happened before...
