Get rid of the "M" mark after file name in vscode [duplicate]

I don't know if it is a new feature in vscode. But I just want the "1" mark and the "M" mark after the file names disappear:

Does anyone one know how to turn if off?

I checked the new lines in my setting.json, seems that they are not related to this problem:

"explorer.confirmDelete": false,  "git.enableSmartCommit": true,  "git.confirmSync": false,  "editor.wordWrap": "on",  "files.associations": {      "*.json": "jsonc"  },  "explorer.confirmDragAndDrop": false,  "window.zoomLevel": 1,  "workbench.editorAssociations": [      {          "viewType": "jupyter.notebook.ipynb",          "filenamePattern": "*.ipynb"      }  ],  "terminal.integrated.inheritEnv": false,  "python.languageServer": "Pylance",  "markdown.extension.preview.autoShowPreviewToSide": true,  "workbench.sideBar.location": "right",  "files.autoSave": "afterDelay",
