Field Assignment is not happening

Hi there

I need your help ,I have created new tables and  assigning them in the existing access sequence  , for adding this tables , i needed to reassign previously assign table to new access sequence , while reassigning , I change the access number of  “902” table , before it was at Access number 10 , now I am trying to assign it at Access 14 ,

Rest of the tables are fine  , but when I am trying to assign this 902 table at access 14 , I am not able to do the  “ field assignment “ ,

Step 1) i assign this table to new access seq( in this case its 14)

Step 2) i click on "Filed " few times to do the field assign , the window opens but i cannot see any field and its comming blank , please find  Screen shot in attached PDF
