I'm building my resume from a template I found online for Adobe Illustrator. When I copy the line and use in somewhere else, then the line thickness increases automatically even though its the same line that is copied. When I'm moving the line around, then line thickness changes for different areas as I hold the line. It becomes thin for some part and thick in others like there's a mask that is thicking the line for a particular area. The line below education is copied from above one and used, but somehow it looks thick in exported pdf.
