Disabled markerly but it still shows the social sharing icons

Hello,
I installed Markerly and for some reasons I had to disable it. However, the social sharing icons still appear on the images as if markerly was never disabled. I have deleted the plugin, deleted my cache but it didn’t help.

P.S- the reason I needed to disable plugin is that when an image is shared, it picks the featured image of the page instead of the image which is clicked to share. I’m running a contest where all the contestant images are shown on a page. I wanted to allow the contestant to share their image on their social profiles.

Thanks,
Nishan
