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#)?
