I think both products have same functionality, except the difference in licensing.
When you say SpaceClaim and ANSYS SpaceClaim, which license do they refer to?
I have SpaceClaim whose license falls under Discovery licensing. I opened the bends library folder and created a copy of sample.csv. I named the copy as sample2.csv. I then closed the SpaceClaim session and reopened it. I was able to see both the file names under Options panel. See below snapshot.
Can you try copying the sample file and see if that shows up in the Options list?
