Pin It button appears without being called!

I am experiencing some strange behaviour with this plugin –

The Pin it button appears on my posts twice without being called –

https://www.fitnesstep1.com/best-spin-bikes-2016-recommendations-and-expert-advice/ (ctrl or cmnd + f “pin” to see it)

I have it once at the top and once just floating at the bottom,

Any ideas ? any known issues with that ?

Thanks,
Suumit
