First, try to find those records directly in the Incident Task table. Most probably they were deleted or you don't have the rights to see them.

Hello @Prashanth1607 

You can use getDisplayValue() method to get the number instead of sys_id.

Thanks!

Ps. for a table there should be just 1 column that has display = true

Be sure only 1 column has display = true

Here is an EG:
