Social Media Buttons disappear when trying to add pinterest button to images

I’d like to add a Pinterest Pin it button to an individual image. I’ve tried to do this every way I can think of. I’ve used multiple plug-ins and also just added the code from the Pinterest developer website for single image and for page.

No matter which way I do it, I lose all my other social media buttons (Facebook, Twitter, Google+) that are supposed to be at the bottom of the post.

Is there any way around this?

Here’s the page I’m trying to work with: https://wonderfilleddays.com/best-read-aloud-adventure-books-boys/ The image I’d like to pin is at the bottom. I’m not sure why you’d need to know this, but just in case.

Thanks!
