Some MenuItems are missing for Project Management and Accounting Module

HI,

 Today ,I found a strange thing with Project Management and Accounting Module(PMA) in my sandbox Environment. There are some menuitems are missing from Area page of PMA module & some options from Forms, some of examples are shown below:

1. There are no Hour, Expense & Fee under Journal area :

2. Under Project Group , i can't found all ledger Options & Estimate Fast tab :

PMA module is behaving unexpected on sandbox server even i haven't any customization for this module. Please suggest.
