[Koha] Customizing Bibliographic Frameworks

[Ms. Naveen Ali]

Dear All, 

I am customizing a bibliographic framework for our library. 
I have changed the 'Text for Librarian' and 'Text for OPAC' fields for some 952 sub fields such as $t, $f, $i etc. 
The changes are visible in the Edit Items Form. 
However when using Item Search or viewing on OPAC the customized labels are not shown. Rather the default labels are shown. 
How do I resolve this. 

With thanks and best regards, 

Naveen Ali
