I've downloaded and am using the VNX 5300 stencil/shape from https://download.emc.com/downloads/DL38235_VNX_Visio_Stencil.zip (I had to create a free account to download it).
I can hit F2 to edit the text, as normal, but it will not display. On other downloaded shapes/stencils, if I right-clicked on the shape/stencil, I would have the option to hide/show shape text, but it doesn't exist on this one. I have looked in the shapesheet data, and "hide text" is already set to false. In developer options, the text is not protected.
Is there a way to force the text to display? I hope to learn how to fix this problem, rather than band-aid it and merely add a second text box.
