Related list records missing..
Hi !
we have created a qeueue and automated the process that everytime queue is created ,related list should show records on defined objects ,but 2 objects are showing details with related records not other 2 . 
Already checked defined relationship (master detail,look up) and checked page layout too ,no issue there.
What might be possible other reason for missing records
Thanks in advance
