v7.9.5

This is a bit of an odd one… see the screenshot.  
Initially, ValveName was an internal property that was bound to an expression. Then I deleted it, but decided I needed it after all straight afterwards and undid the deletion, however how it’s a template parameter, and is still bound to the expression, with no way to unbind it 🙂

Edit: It actually shows that it’s template parameter in the properties editor. Creating it again in the Internal Properties and removing it from the Template Parameters and pressing OK then fixes it.

The point is that the undo action didn’t restore it to what it was
