Grid (Serializer Grid) skip one record while loading

Question

I am loading a serializer grid with record but it skips the very first record it is returning array correct

Grid

Code for my grid is working like this ->it loads the answer related to a question. ->the helper function returns an array related to a question the grid is suppose to load those answers in it. ->I have tried other ids it is working for other but when i pass id=1 helper data returns correct array but only one record is loaded but not the other one.

i.e for id=1
it returns =[1][2]
but grid only loads the [2] and skips [1]

My Grid Code is

Answer 1

Found my solution I removed the

 $collection->addFieldToFilter('answer_id', ['nin' => $this->getRequest()->getParam('id')]);

from my code now its working fine
