Asset Summary under Personal tab section?

Personal/Deductions & Credits/Retirement and Investments/Other Investment Expenses

At the end of this walk-through, after I enter Investment Expenses and click Continue, suddenly I'm presented with a screen called Asset Summary, where I'm given the opportunity to enter and/or edit (I assume for assets being carried forward) assets used for business if the amount of business use of said asset has changed or stopped altogether. I can also Add an Asset.

First, why is this business-y thing under the Personal section? And why is it at the end of the Other Investment Expenses subsection? And where would any pre-existing business asset entries have come from? Here last year? The Business tab/section last year?

Very confusing.
