Taking an illustrator pattern and using it in Photoshop

[@stylepalettefashions899]

Hi! This video was of great help to export the patterns from AI. I have a quick question even though I am following step by step instructions I am still seeing white lines between the pattern. Can you please suggest the solution. Thank you
