"Spiderweb" lines in production in ContextCapture update 9 (pics)

In the new version of CC (update 9) we are constantly getting a strange phenomenon of lines which radiate from a certain point in the models, see pics below. This happens when we make the model bounds from a polygon in a dgn file (new feature of update 9). These lines do not appear when retouching the tiles. How can we avoid these lines, or erase them in retouching?
