On Fluid: After Modifying Accounting Defaults on a Report, at What Point is this Change Saved?

After making a modification in the Accounting Defaults on an expense report while on Fluid, at what point does this action become saved? I noticed in Fluid there does not appear to be a Save or Save for Later button or link for the user to click at their own will like they can on the classic create report page. Does this type of modification become saved when clicking the Continue button from the accounting defaults - distribution line page, or when clicking Done button from the Accounting Defaults page? Or does some other action save the modification?

1.  Click Expenses tile
