I'm looking at my library: It seems to have two different versions of the same assets within the Motion Graphics Intro Clips folder and the Motion Graphics Lower Thirds. In each case, for example, I have a file named "cornercircles" and another one named "cornercircles-91. The same duplication is in the Lower Thirds: basictext-01 vs. basictext-01-91. What's the 91? A different version for Camtasia 91? Every asset in both folders has two versions.
