Cause
NUMFORMAT in SQLPLUS session is in other format causing the problem.

Solution
1. Check the NUMFORMAT value.

Show numformat
numformat "999,999,999"


2. You need to set the numformat empty as default value:

--Set
SQL> set numformat ""
--Verify
SQL> Show numformat
numformat ""


3. Check the AWR report again.
