[Weird white lines with EPS file format]

Thank you, firstdefence. Your suggested fix worked perfectly. In my defence (pun intended), I'm not a graphic designer. I'm a learning experience designer. Again, thanks, firstdefence. 

[Weird white lines with EPS file format]

My client has provided me with 20 vector graphics as files in the EPS format. When I open them in Affinity Publisher 2 I see a grid of thin white lines across some sections of the graphics. I need to find some way of removing the white lines so that I can use the vector graphics I've been given. Is there a workaround for this?
