Resizing grouped objects - Storyline 360

Resizing grouped objects no longer works. Some items resize, others expand tremendously and reposition themselves around the screen. Undo will often not revert to the pre-resize state. The only way out is to close the file and reopen a saved copy.

I have a presentation that I resized multiple grouped objects, most with triggers and animations. It worked fine. After the last 2 updates, this no longer works.

Is there any fix or workaround for this?
