A question about reference number sorting [resuelto]

When I look through the Danish banknotes sorted by reference, the first 2 banknotes below are on the 1st page of the Numista banknote catalogue, while the last 2 are on the 3rd page, even though they should be next to each other.   



Is this separation simply a question about the order in which the reference numbers have been put in (P# SIEG SD# vs. SIEG SD#  P#)?
 

P comes before S in the alphabet, simply as that.

Thanks, I guess I'll go request a reordering of the numbers then
