Options | Editor | Formatter | Custom tab window not showing vertical scroll bar and non-working Expand/Hide function. (4235023)

In Options | Editor | Formatter - Custom tab the panel with the tree, the nodes cannot be opened and closed properly and the vertical scroll bar does not display if the list is longer then the window.

With a new install or a fresh profile settings, the nodes and scroll bar seem to work, but the issue comes back later. Resetting the Toad options all the time is not an option since each time, personal configurations for the settings are also reset, and the issue still comes back.
