These 4 glycans in the gp builder, as well as any O-links that contain poly-lactosamine, have the incorrect connection (b1-4) between the repeats, it should be b1-3.

e.g. this
DGalpb1-4DGlcpNAcb1-4DGalpb1-4DGlcpNAcb1-2DManpa1-3
should be
DGalpb1-4DGlcpNAcb1-3DGalpb1-4DGlcpNAcb1-2DManpa1-3
The 2D images that show the linkage info when you hover over are also incorrect
