Plugin eats up my social sharing buttons

Hello there,

When I activate “thumbnails for excerpts” on my homepage. All my social sharing buttons disapper on homepage and only appear on single post pages.

I tried many plugins, but same result. So, the glitch is in thumbnails for excerpts.
I want social buttons to show on homepage even when its activated.

Any help?

thank you
