MOD output strange behavour

[DesignBureau]

The MOD output of one of my tracks does not output modulation values. It look like it's outputting sort of envelope linked to thetrigger or notes. I can't get behind it. In an other Empty pattern of the same track it works fine, as soon as I put in a note and trigger it does not respect the mod value any more. I resetted effects in Nerd Page and by SPFX 00A.
