New button disappears from Related List after one record submission

[Ketan Mittal]

On the project page, In the related list, when I try to create a Benefit Plan via clicking upon the New button, the record gets created and shows up in the related list. However, the New button disappears for me to create another one. 

 

Why does this happen ? Is there a script running ? There is no list control applied.

This is not OOB behaviour, as doing the same in my mostly-OOB Tokyo PDI results in the New button still being visible and operable after adding a record.  In the List Control, make sure you don't have anything in the Omit new condition field, which you may have to add to the form to view.  Also check UI actions named New to see if there is a custom one for the benefit_plan table that has a condition to hide it if there are any records.
