Cannot dissable infill

[shadowfiend 9]

Hi,

I am trying to disable infill like I have done many times before, but since version 3(ish) Infill Density just keeps jumping to 20%.  I have a small part that I want to be hollow, but Cura 4.1.0 is refusing to cooperate with me.

 

I feel like I'm going crazy please help!

I found it eventually.  There is some strange behaviour with the input fields going on.  So upon changing the value in the input field, the enter key does not set the changed value.  The TAB key does set the changed value.  If the value is changed and then the mouse is clicked elsewhere the change is reverted back.

 

Has anyone else found this behaviour to be very confusing?
