How to store a uint[] memory inside a struct in solidity

Question

I have the below code

struct Ticket {
        uint256 id;
        uint256[] numbers;
        address payable owner;
}


function enter(uint256[] memory userNumbers) public {
        Ticket memory newTicket = Ticket(
            id,
            userNumbers,
            payable(msg.sender)
        );

        entries[id][msg.sender] = newTicket;
    }

However, when I inspect the Ticket object saved, I only get the id, and address.

How should I properly save the userNumbers inside the struct?

This works fine for me. But it does not show the dynamic array in Remix if that is what you mean? However, this does not mean that the array is not there. It just seems like a UI bug/limitation.

I wrote this code to test it:

pragma solidity ^0.8.0;

contract StackOverflowAnswer {

  struct Ticket {
        uint id;
        uint[] numbers;
        address payable owner;
  }
  mapping(uint => mapping(address => Ticket)) public entries;

  function enter(uint256[] memory userNumbers, uint id) public {

    Ticket memory newTicket = Ticket(
        id,
        userNumbers,
        payable(msg.sender)
    );
    
    entries[id][msg.sender] = newTicket;
  }

  function seeTicket(uint id, address _address) public view returns (uint[] memory) {
    return entries[id][_address].numbers;
  }
}

I wrote an additional method just to retrieve the dynamic array part of the struct, and it renders it when specifically selected, I guess:
