Site Origin Button Issues

When I installed Site Origin Buttons in the past, there was no issues.

Now, some of the buttons are not working. When install a new button, it shows a large empty block of space on my page. This also happens to some buttons on my existing pages or posts.

On my homepage, I have used two Buttons. But only one button can work. The other just shows a large empty block of space. When I reinstall that button, the other Button ended up showing a large empty block of space.

I have tried deleting and reinstalling many times and the same thing happens. Only one Button works.
