For example, I created this test homework set including three problems where the second problem is Library/FortLewis/Calc3/14-1-Partial-derivatives/HGM4-14-1-17b-The-partial-derivative/HGM4-14-1-17b-The-partial-derivative.pg.

The second problem includes a 3D graphics (javascript). Then, say, I move the third problem to the second. After that, if I check both "Automatically render problems on page load", "Force problems to be numbered consecutively from one" and click "Save Changes", I then get

From the pictures, you can see that the up-down arrows which allows us to reorder the problems are gone. The only way to reorder the problems again is to go back to the "Hmwk Sets Editor" and click the homework set again.

If there is no 3D graphics in the problems, there is no such problem. You can reorder the problems again and again.

My question is: Is this by design? Or I am missing something here?
