Double Posting problem

This plugin causes any text that I paste in the “Visual” view in the WordPress article editor to appear twice. The first time with paragraphs and the second time without any paragraphs. When I switch to “Text” view, the text pastes only once as expected.

I know it is this plugin causing the problem because when I disable it, this problem is not there and I can paste text once in the Visual view as normal.

Please fix this.
