That is because the uploader didn't change the page numbering on their files... Tbh I don't know why the creators do this primitive mistake of last century of putting numbers like:
0 1 2 3 4 5 6 7 8 9 10 --------- 100
And not do correctly like:
000 001 002 003 004 005 006 007 008 009 010
If the collection was over 1000 than same thing with 4 digits...
This is why you see if you over the mouse on pics 1 10 100 and then follow correctly until the end and then once reach 19 put the pic 2 then 20 and so on...
