difference between je_source_name and user_je_source_name

 hi, i am aware of the difference between gl_source_name and user_je_source_name in gl_je_sources_tl table;
and these columns purpose in other tables also; my question:- i have user_je_source_name as ADI and je_source_name as 1;
from where this numeric value (1) came from even though it should be ADI;

please suggest;
