Windows Defender Group Settings

I stumbled on this older thread here:
How do I remove quarantined threats

and gained a little knowledge on how to regulate the quarantined files allow/delete settings.

I have enclosed a image of my settings and have a question regarding the configure number of days folder.
If I change the value to 1 or more = enabled. If I revert to 0 = disabled. Does it have to have value greater then
0 to enable? Also, what is the configure local setting (above removal of items- Brown arrow)
I have the eicar test file and was testing to see what defender would do and when I click on the file, defender will go into action and depending on if number of days is greater then 0, I get an allow or don't allow choice.
If it remains at zero (0) then, the file is locked up with no option to remove the test eicar file.

Edit: If I change the policy editor and configure removal of quarantined items to zero (0) then it becomes
disabled. In my EICAR test file I only get allow actions in threat history and no option(s) to allow or remove.

Also, I thought that if the setting was adjusted to zero days that anything in the valt is auto deleted.
