if you not use the layer or object which is mapped to 108:0 in your layut , then ofcourse you wont see any problem/difference.
Please check what is mapped there. What layer in the layer map file and what object in the object map file? If you have
duplicate datanumbers there you loose either the layer information or the object information.
The shapes should still be there, but it's possible that they are on a wrong type now.
