Label Text Blank Design View

In the design view I often select multiple controls of the same type using Ctrl+Click to edit a common attribute, like the height of multiple labels. Attributes that are not common, like the label text, are shown blank. If I subsequently select one of the labels the text is still blank. If I exit the project and load again they are still there so not a problem as long as people realise:-

Also see here:

From your example, it sounds like the transition from group selection to individual selection of an item within the group fails to include a full refresh of the attribute display for the newly selected item.

Did I guess right?

That sounds about right, as I say not a big deal now I know but I did edit a few before I realised what was happening

This is the same problem with me.
