Drawing in glyphs

hi all
I’m designing a font and have one issue
my letter in illustrator looks perfect and straight

but when I copy and paste it into the Glyphsapp the line becomes not straight and it doesn’t let me fix it

is there anything I can do about it

The piece is too small. The nodes will be rounded to the unit grid. You can either accept it because it is so small and only visible zoomed in, or remove points, or find positions for all points that happen to line up on the grid.

What is your intention with all those points?
