[Koha] Date Field not visible in Koha 2.2.9

Dear Friends, We just installed Koha 2.2.9 in fedora core 4. While "Add Item" information after cataloging a document , not able to enter the date in "v - Date acquired" field. This field seems very small. I attached picture here, http://www.asbindia.in/library/images/edititem.gif I have another doubt, How can I remove unwanted fields from Add Item part? Thanks in advance Vimal Kumar Asst.
