Shadows on ground plane not showing correctly in render

[vanwiggeno (vanwiggen)]

Hello,

I am trying to render out an array of objects like these shown. Half of them work fine but the other half are having issues with their shadows. There are no objects below the object but for some reason once it is rendered, the ground plane appears to drop. This is a transparent background render with show shadows only selected for the ground plane.

Thanks in advance

Does it work better when you switch ground plane to manual instead of automatic?

Works perfectly. Thank you
