ORA-01418 while moving SYS.AUD$ Table from SYSTEM tablespace

I created two table spaces. One for the data and the other for the index. During the move process I selected the two table spaces then press the Continue button. Here it complained about the Index and gave me the ORA-01418 error.

Ora-01418 means "specified index does not exist"

Which table and index are we talking about?

I am moving the SYS.AUD$ table from the SYSTEM table space. In this process you are given a dropdown list box to choose two tablespaces. One tablespace is for the new location for SYS.AUD$ table and the othjer is for the new location for indexes from SYS.AUD$ table. I PRE-CREATED TWO table spaces and choose these two tablesapces as the new locations. It is complaining about the new tablespace by giving me the ORA-01418 error.
