[LH2265| LH3051] The "List" function on the Formate Bar doesn't seem to be working right

Once a list type is selected the only way to change to another list type is by clearing the current selection, by clicking the list icon next to the drop down arrow, or clicking none in the drop down list and then making another selection; otherwise nothing happens when you click a new selection.

Also, the tabbed list (1.1, 1a) don’t seem to be working at all. They cannot be selected as the original start to a list or switched to from another list type.
