Comment 3 for bug 1654529

Adding a note that I tried these specific call numbers on the community demo server. With the classification scheme set to LC, I saw the following in the call_number sortkey field:

QD305.T45T55 2013 - QD0305 T45 T55 02013
QD31.2.A75 1989 - QD00312 A75 01989

The call numbers did sort as expected in the shelf browse. I suspect the issue you're seeing is that the LC class scheme wasn't applied to one or both of the call numbers.
