If you place the dimensions after saving the view, this can happen. You have two possibilities to resolve this issue. First and foremost, in the view map, you should have two views with the same name. Click on the first one including the dimensions and go below the view map, you'll find a view with the same name. Put the cursor on it, and make a right click on to redefine it by clicking on "Redefine with Current Window Settings."
The second option is to link the drawing you have in the layout with a right click on "Link Drawing to..." to the view, in the view map, including the dimensions.

@reidweber Extend the 12' dimension to include an additional node and see if the 12' dimension still disappears. If you recreate the dimension does it still disappear? If it does it would be worth sending to your local GS support as another possible dimensioning bug. I currently have an issue with certain arrow marks being present in the View but not on layout.

It seems to be that specific dimension section won't show up. I double checked that this is the correctly linked and I placed a new version the same view on the sheet without any changes.
The new nodes on that dimension show up, and eye droppering its parameters and drawing a new dimension string works, when I copy that specific string though using ctl+d + It doesn't show up still. Not a big deal for this one instance to draw a new dimension string, but I don't want this to happen again for a larger project.
The image below shows the two "missing" dimension strings that, two copies, the others were "eye droppered' and redrawn.
