Shape formula lost after grouping

Check the code bellow. After grouping, the formula for shape.XForm.Height.Ufe.F is lost.
How to keep the formula after grouping ? It is unconvenient to save all formulas related to a shape and restore them after grouping.

long shapeId = page.DrawRectangle(1, 1, 1, 1);
Shape shape = page.Shapes.GetShape(shapeId);
shape.XForm.Height.Ufe.F = “GUARD(TEXTHEIGHT(TheText, Width))”;

Aspose.Diagram.Shape[] ss = new Aspose.Diagram.Shape[1] { shape };
Shape group1 = page.Shapes.Group(ss);
