I did some proof with and without the filter and the vignetting decrease enormously but still remains, no blackness but some darkness of the colors.
Someone here having the issue ?

The thick filter would explain it. My lens and kit are upstairs. But I recall the hood comes in two, separable parts - one that is effectively a step-up ring to go from the 58mm filter mount to about 67mm, then the metal hood. Clearly, recognition that the angle of the lens would not allow 'normal' filters was part of the original design understanding of it.
Also, it is possible to get bother with the two parts biting together too tight, so some care in use is needed.
BTW: I can place at least one normal 58mm filter on it on K3 without vignetting.
