Stems of n, h looking thin compared to the rest of the letter at smaller sizes

Hi,

So the font was working fine (I think) when I made all the light weight lowercase and when I created a black master I suddenly noticed that the stems of n, h, etc are looking thin compared to the other vertical stroke. Both are 30 units. Attaching screenshots. Just want to make sure what the problem is before I move forward. Is it hinting related?

Edit: I am new to Glyphs and designing a typeface.

That can happen if the path has the wrong path direction. Can you check if it is counter clock wise?

Fixed! Thank you so much. I just hit “Correct Path Direction”.
