Sharing plugins not loading after site nav, ruby on rails site

Under apps I’m trying the Share Buttons app. On initial page load from a cold URL, the share buttons come up. On inter-site nav by clicking on the links, the share buttons do not come up. If you reload the page you are on, the share buttons will come up.

It’s only on the inter-site navigation. I tried the other plugin with similar functionality (AddToAnyShare) and… identical results.

What do I need to configure on my site for these to work correctly after inter-site nav links?
