The screenshot with the two F naturals and E was made when I imported the ABC file with the formatting code in front of the music code. The ABC file looked like this:

%%%%topmargin 1 in.
%%scale 1
%%topspace 0
U: m = !breath!
U: h=!slide!
U: w=!wedge!
%%musiconly

X:111
T:Gracie's Tune
C:Elizabeth Durning
L:1/4
Q:1/4=120
%%scale .8
M:4/4
K:D

It was all the formatting code before the line X:111.
