Problem with plugin

Hello guys! Thank you so much for this amazing plugin!
I was trying to set it up and then it turned out like this:
https://thenoirportrait.com/2015/03/04/interior-design-black-home/?preview=true&preview_id=4025&preview_nonce=61e10918f3&post_format=standard

In that page you can see a tiny text that should be the “tweet this” link, I only selected “with black you can’t be wrong” BUT the rest of the text also changes, I never touched any codes, only the settings options.
I uninstalled the plugin to install it again but nothing happens, please help! I REALLY WANT TO USE THIS PLUGIN

Greetings
Tatiana
