HDR light - ERROR -

Hi every one,

I have an issuu with HDR lights in my scene. I am pretty new using ue4 and I do not know how to fix it. I have an interior scene running on my iMac and the HDR lights don´t work properly. As you can see in the image the HDR light reflected on the floor shouldn´t go throught the column. I have tried it on my laptop and this error doesn´t happen. I don´t know why the difference between them being the same scene. Besides, when I run the scene on my laptop the lights are pretty much brighter.

I really appreciate whatever comment.

Thanks!
