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

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

namespace VendorNameSpaceBlockAdminhtmlAnswerTab;



use MagentoBackendBlockWidgetGrid;

use MagentoBackendBlockWidgetGridColumn;

use MagentoBackendBlockWidgetGridExtended;

use MagentoFrameworkAppObjectManager;

use VendorNameSpaceModelTopicsAttributeSourceStatus;
