Grid field display using CDT

I am trying to display a grid field using a Employee CDT which has nested Skill CDT, association between these two CDTs is one to many. For an instance it's like one employee with multiple skills.

When I am trying to display it says the total count of grid is different from the number of rows to be displayed.

Can anyone help me by providing multiple solutions to solve this issue?
