All Short Cut Key Unassigned not working

[DHPATEL177]

I am Un-assigning the keyboard short cut fields but somehow when i reload the url then it again comes as assigned. My end goal is to disable all shortcut keys. Please see the screen shot.

What are the steps to reproduce?

Go to Key Shortcut unassigned "Delete Config Selection","Show Dashboard","Select All Config Nodes".
Reload the url.

What happens?

After reload the url then again this 3 keys become assigned.

What do you expect to happen?

this 3 keys should be unassigned.

Please tell us about your environment:

• Node-RED version: i have created image of node red using docker and hosted it on azure kubernetes.
