Horizontal lines disappear after using indicator

[eswap0]

I installed this indicator from here and horizontal grid (set to 100 value) disappeared.
Can you guess any reason?
Thanks!

Not sure I follow, it displays the last traded price as a horizontal line. When you scroll back and this price level is not visible anymore, the line won't display, too.

Sorry I didn't explain it properly.
I have my chart with Properties-Horizontal grid lines enabled.
I can see them, every 100 pips.
I add CurrentPriceLine indicator to my chart and all horizontal lines are gone!
Thanks.

Ok, thanks for clarifying - please use the first posted PriceLine.zip then, the horizontal lines should stay then...

Solved with the first zip.
Thank you.
