First and third line seem to be the same note (26b without security thread), users from first to be moved to third and first line to be deleted.
Same is sue with 500 Rublei
I guess the issue with the yearlines of these notes is that the year 2000 is printed on all the notes, but some (without thread and for higher values with segmented thread) were only issued later. I guess they should all be marked as 2000, with year of issue in the comments?
These pictures have to be switched (same author on both pages) (having issues with saving pictures, so cannot do it myself right now)

With all the notes having printed dates not corresponding to the year of issue the sequence is a bit mixed up (eg. 2000/2012 vs. 2009/2016) ... annoying country
edit: link to 500 rublei corrected
