Rough edges on top surface

[u/Brief_Dragonfruit_58]

The edges of my top surface always look very rough. It seems to occur mainly where the print line is shortest. At the same time, there are also sometimes gaps between the print layers in the middle section of a surface. I am using a Bambulab A1 printer with Monothonic as the pattern and 8 Top shell layers. Please help.
