You are supposed to see the same result. maybe you should set your screenshots to show the exact frame side by side so you and us could really be sure that it's different. in the screenshots your provided, we see different frames and your mask path visibility is on, so we can't tell if there is a line or there isn't.
You have two strokes applied to your path/ mask and maybe the second one is also set to paint on the original source. Check that. I'd probably also use separate layers for the two words, so things become a bit less confusing and you can work with one stroke per layer.
As Mylenium said, delete the second stroke effect. There is a 90% chance that is where the problem is. You can check by selecting layer 19, pressing the U key twice and turning off the second stroke effect. Then deselect the layer or turn off the path visibility and see if the stroke is gone.
