Wavetable synth bahaviour. (Modulator? Glide?)

[Capitan Mission]

Hi, i'm enjoying the new Ableton Wavetable synth, I really like it. My doubt is about some behaviour that I cant control, the output sound is not what I want and I have some clues of what it can be:
The clip is 8 bars long, one note (A0) extending the 8 bars, and in the 6th bar a sequence of 4 short notes (A,G,F,D, octave 4) above the A0, and the problem is that if I start playing for example in the 6 bar the glide (and or attack) of the notes is a lot sharper than starting at the beggining (I want it that way, "sharp").
The preset in question is "Effing Bass" , I think that is something about the modulation matrix but i dunno...
Thanks
