Debugger code (debug.datatables.net):
Error messages shown: none
Description of problem: I have some rows with cells containing multiple values. The counts appear correctly in the search pane, but when clicked, do not show the rows containing the multiple values. See row #1 which has two "Offices". Any suggestions?
