Weird results from Ladybug

Hi, I am getting some strange results from Ladybug. 
We are currently working on a project of an industrial facilty in Recife in Brazil, and I am creating some shadows diagrams for a presentation.

The results look fine in the morning, but when I set the time after 12pm, the angle of the shadows start to look strange, not corresponding with the position of the sun in the sunpath. 

I took two screenshots to illustrate the problem. The first one uses the Rhino sun for shading (with the correct location data), and the second uses Ladybug Sunlight analysis.

Would love to know what you guys from the forum thinks about it.

Is it a bug? A mistake I made? Just the wrong impression from the sun path being so small and close??
