Facebook share creates gibberish in the description box

Yesterday, all was working fine, but today, when i try to share a new blog post using the share buttons (to Facebook) it comes up with weird characters and numbers in the description box.
I have tried everything i know how to do, but can’t find a solution. I’ve emptied caches, logged out, deactivated and even removed the social sharing plugins, tried new ones–among other things. Nothing helps. Here’s a screenshot. https://kellijaebaeli.com/wp-content/uploads/2017/04/ScreenHunter_1161-31-Mar-17-17.20.jpg
