The most likely reason that your tables are being created with a
PCT_INCREASE of 0 is that the default storage parameter of the tablespace
is set to 0. To find out, try:

SELECT * FROM DBA_TABLESPACES WHERE TABLESPACE_NAME = 'tablespace_name';

When an object such as a table is created in this tablespace, it will take
the default storage parameters if not supplied in the CREATE TABLE
command.
