VIDEO THUMBNAILS impacting on non-video post thumbs

Hi, since installing Video Thumbnails plugin I have noticed an issue with some non-video post thumbs on my homepage have lost their url redirecting abilities to the post page they are originating from. The thumbs associated with videos are redirecting beautifully, but not the non-video thumbs. Web site home page is: https://www.golftoursabroad.com
I’d be very grateful if someone could sort this issue for me.
