Workspace "Save" button grayed out after 8.2.2

After upgrade to 8.2.2, “Save” button is always grayed out on workspace changes, though “Revert” button is clickable after changes. What I did was clicking “Remove Feature” button on the left sidebar in the “Additional Features” area and removed “Text Metadata”. I even created a new workspace, add “Text Metadata” feature, save, then edit to remove “Text Metadata”, “Save” button is not lit up to save.

i will take a look at this strange behavior and see where the issue is coming from.
