Not able to see the updated values in react after creating a group

I am trying to perform a simple exercise, wherein I am showing the data from the local JSON file saved in my folder, and then reading it to show the data with useSate, such that when a user clicks in he can edit the author and location filed and save it.

The issue I get is when I save the data in my group or location it does not populate the new value, however, it just removes the new value, but when I filter and select all values from the dropdown I can see the values in there.

Can anyone please let me know what is the missing part here? I want to achieve the task that when a user updates the value on the author group or location group they should be there with the new group value.

Please the link to the code below and a working demo on codeSandbox

The source code for author group component I tried so far ;

    import { useEffect, useState } from "react";
import {
  Container,
  Accordion,
  AccordionSummary,
  AccordionDetails,
  Typography,
  Button
} from "@mui/material";
import ExpandMoreIcon from "@mui/icons-material/ExpandMore";
import EditIcon from "@mui/icons-material/Edit";

const Authorsgroup = ({
  posts,
  groupDropdownValue,
  setShowForm,
  setPostId,
  showForm
}) => {


  const authorGroup = posts.reduce((group, authorgroup) => {
    (group[authorgroup.author.replace(/ +/g, "")] =
      group[authorgroup.author.replace(/ +/g, "")] || []).push(authorgroup);
    return group;
  }, {});

  const [authorGroupValues, setAuthorGroupValues] = useState(authorGroup);

  useEffect(() => {
    setAuthorGroupValues(authorGroup);
    console.log(authorGroupValues);
  }, [groupDropdownValue, showForm]);

  return (
    <>
      {/* all gorupby authors  */}

    {/* show group of Tapesh */}

      {authorGroupValues?.Tapesh.map((post, index) => (
