cannot add a value when set the gui to canvas mode

[Xposeder]

when set the gui to canvas mode, can not add a new value。It will be no reactions and
stuck. One solution to this is first dispose a value and then add a new one at the sametime.

Just dispose a value in the canvas mode also works.

I tried to reproduce the problem on your example, but it worked fine, so I think the problem might be somewhere else, sorry to bother you, I'll close the question.
