Repro Steps:

1) Create a Page
2) Introduce a Canvas element to the RootGrid of the Page.
3) Introduce a Rectangle to the Canvas.
4) Remove the Stroke (Clear Local Value, and remove the Thickness (Set Value to '0')
5) Dimension the rectangle to be 256x256
6) Using the Selection Tool (V), click-and-drag the Rectangle so that it is Vertically-Centred in the page (A red guide will appear when snapping to the vertical centre of the parent element)
7) Using the Selection Tool (V), click-and-drag the Rectangle so that its left edge is aligned to the Horizontal center of the parent element (A red guide will appear when snapping the left edge)
8) Right-Click on the Rectangle, and from the 'Path' submenu, select 'Convert to Path'.

9) Select the Path Selection Tool (A), and whilst holding [Ctrl], click-and-drag the two right anchor points of the Rectangle that has been converted to a Path, as to give the two right anchor points a curve. (any curve still is fine)

10) Duplicate the Rectangle by selecting the Path in the Navigator, and pressing [Ctrl+D].
11) With the new duplicate rectangle selected, navigate to the its Properties Panel, and in the Transform/LayoutTransform section, set its Scale X to '-1'.

12) Drag the duplicated and horizontally-rotated Rectangle to the right, and drag it until its right edge is aligned with the original rectangles left edge. This will be appear by a red guide appearing when the two edges meet.

13) From the Navigator, hold [Ctrl] and select both rectangles.

14) With both Rectangles selected, right-click on either of them, and from the 'Path' submenu, select 'Make into Compound Path'.

Observe how the shapes are moved from their set position, and compounded in a different position.

Expected Results: Compounding multiple Path compounds them at their position when the Compound is activated.
