Italics and Clear button not working in React Draft WYSIWYG

Question

Italic and clear option in text editor are not working. I have tried removing and installing wysiwyg text editor but still I cant use Italic and Clear toolbar buttons. I am able to press it i.e. it is clickable but there is no change in the editor state. Can anyone help me with this ?

   return ( <div className="editor">
      <Editor
        handleBeforeInput={handleBeforeInputFunction}
        handlePastedText={handlePastedTextInput}

        toolbar={{
          options: ['inline', 'blockType', 'list', 'textAlign', 'colorPicker', 'link', 'embedded', 'emoji', 'image', 'remove', 'history'],
          image: {
            previewImage: true,
            urlEnabled: true,
            uploadEnabled: true,
            uploadCallback: uploadImageCallBack,
            alt: { present: true, mandatory: true },
          },
        }}
        toolbarClassName="toolbarClassName"
        editorState={editorState}
        wrapperClassName="demo-wrapper"
        editorClassName="demo-editor"
        onEditorStateChange={onEditorStateChange}
      />
    </div>
  );
