Grey Edges on Corners of Product Cards

[ProconMarketing]

Hi, there are grey edges on the corners of my product cards. 

See image: 

I have played with the rounding and the shadows. It still shos. Any reason why this might be. 

It is subtle, but is it possible to remove it?

Please help.

Thanks in advance.
