Hello 3D_Scan_Fan,
Negative texture coordinates are still present in the model that you have imported to 1.1 version of PhotoScan. But this time no values above 1. The difference seems to be related to the orientation of the model in the coordinate system space. In one case Y is pointing "up, in another - "down".
And I still see artifacts by the sides of the texture atlas, see below (but now they are not crossing the picture, seems to be related to the orientation of the model):
