Problem with spatial indexes after impdp import

I am getting some errors indicating that there are problems with spatial indexes.

However the log file (see below) does not appear to specify which spatial index is causing the problem.

Is there some way of determining what indexes are at fault and how I can identify corrective actions to take?

Thanks in advance.
