After upgrading Spectrum from r9.3H01 to r10.0, all LACP port aggregation tables that I've viewed have been blank. It will indicate, for example, "Displaying 28 of 28" above the table, but there's no data displayed in the 28 rows listed. The only thing I see is a "Aggregator ID" of "0" for each row. The search and spotlight capabilities do list the LACP configured devices as they should.
The thought has occurred to me that maybe the SNMP v3 configuration is preventing successful queries of data to populate the table, but I don't know if that's the case.
