Oracle 9 - tablespace default storage

Hi, I am having a strange problem with the storage parameters in Oracle 9.2.0.1 database.
I create a tablespace with some default storage parameters but when i am adding a table to the tablespace i can not override the NEXT statement? No matter what i set the NEXT storage parameters to, it is always the same as the tablespace default, the INITIAL is overriden just fine. I have included my script below, can someone please point out what could be wrong.

Thanks in advance!
