Failing to open layout option on Dashboard

Hi everyone, has it ever happened to you that when you click on the "layout" button to change the position of the widgets on the page, nothing happens? It happens after a while I'm working. For example when first happened I unistall and reinstall everything and it starts working fine again, but after a few hours it stops showing me the layout option of the dashboard.
My nodered version is 3.1.9, I'm working on a Raspberry pi3 B+, I have installed the following library:
node-red
3.1.9

  • node-red-contrib-buffer-parser
    3.2.2
  • node-red-contrib-mdashboard
    2.19.4-beta
  • node-red-contrib-play-audio
    2.5.0
  • node-red-contrib-ui-led
    0.4.11
  • node-red-dashboard
    3.6.5
  • node-red-node-pi-gpio
    2.0.6
  • node-red-node-ping
    0.3.3
  • node-red-node-random
    0.4.1
  • node-red-node-serialport
    2.0.2
  • node-red-node-smooth
    0.1.2

Thanks for who want to

Welcome to the forum.

You cannot have both dashboard and mdashboard installed. Uninstall mdashboard.
