Comment 1 for bug 1993850

Occurs in 3.10 as well, and also affects the Default Library. I also tested deleting values from Search Preferences to see if the subsequent values input in Workstation > Administration would carry over, but they didn't. In this case, though, clearing cache did reset to the Workstation > Administration values.

I tested another scenario on a new workstation where the Default and Preferred had not been set in either place. If I clicked on Search Preferences first but did not input any values, and then made changes in Workstation > Administration, the changes would not carry through, so in this case, it may appear to the user that there is a bug with Workstation > Administration settings. Search Preferences automatically update as soon as you open the page so there's not a way to avoid saving the null values in this scenario.
