Explore > My records and choose a particular grid 'circle'. If there are more than 30 records (the default page length) then the first 30 of NN records are displayed correctly. However if you hit the Next button to display the next 30 for that locality then the current selection is lost and it displays the next 30 for all of my records instead. This makes exploring records for well-worked sites almost impossible. The same bug is manifested when using Explore > All records.
