In the layout editor for a custom model. Running 2018.50, Windows 64bit.
It seems like the Face Definition "Select Nodes" editor is not properly updating the "Face Outline" grid when you dismiss the "Select Nodes" dialog via Ok.
The result is if you double-click on a Face Outline row, select a few nodes, then click Ok in "Select Nodes" and Ok in "Face Definition" the changes you made in "Select Nodes" won't be saved.
If you however use "Select Nodes" to author the nodes, then Ok it and change something else in the textbox while "Face Definition" is still open (e.g. add a "1," in the beginning of the line) then click Ok, it will save everything.
