text border blendmode difference

HI at all
I tried to create a Motion Intro. I have 2 exact same text-layer with blendmode difference. But one text is white and the other is blue. The background are blue and white shapes.
With this setting i can achieve, that the text-color adapts to the background. that works just fine.

But my problem is, that the text has really ugly borders in a orange color (complementary colour). I don't understand why. the text-layers have the exact same parameters (except color).

Does anybody has an idea how to get ride of this borders?

I have tested it in photoshop. there it works just beautifully.



thanks.
