Why are thin lines showing below spaces in DrawText when scaled?

i have a font that looks fine in the font preview but when I render it on the HUD, there are thin lines under each space.
I have scaled the text in the blueprint DrawText node to 0.66
With a scale of 1 the lines don’t show up.

I could just make a new font with a smaller base size, but I was wondering why this occurs.
