This change works in my testing, but I think that the user interface is unclear. I think a tabular structure will be clearer, and have created this example. There is one row for each list and a row at the end for the "none" checkbox. It also has explanatory text for the default. I think using "default" (or maybe something else) is clearer than "pre-select" because "select" is already being used for choosing the lists to include.

Yes, your version is definitely better, updated
