how do I debug bus signal hierarchy

This is my error message.

Error occurred while propagating bus signal hierarchy to input port 2 of the block 'SMFRMK_FW/Bus Creator'. The propagated signal hierarchy is inconsistent with the bus object 'SYS_INFO_BUS' specified on the block. This bus object directly or indirectly has a bus element with data type 'PH_PRS_INFO' that does not match the propagated signal hierarchy.
