Sorry if I am repeating myself as I may have mentioned this issue elsewhere. It concerns the 3D Model Manager which is really confusing to a newbie like me. Please  look at the image attached and notice the parts I have indicated in red. I do not understand what the list on the left is supposed to represent. Some of the titles seem to be a concatenation of two of the same titles and sometimes two slightly different titles. There is no indication of what these two parts are and I can find nothing in the FAQ / Tutorial that explains them. Anther strangeness is the fact that Chinese characters are sitll evident within the 3D Model Manager even though my language preference is English. Can anyone offer a reason for this strangeness?
