Lightmap problem

Hi guys,

Anyone can answer me why am i getting this weird black shades on the model and why the UV seems to not understand the SEAM i marked and closes the texture on the wrong spot?

The black shades problem i solved by deleting the base of the cilinder, it was somehow messing with the normals, but the UV still on the wrong spot.

I’ve rotated the cilinder. It solved. Sorry to bother.
