Save On Compile options in the Compile dropdown menu are grayed out in the Level Blueprint

Save On Compile options in the Compile dropdown menu are grayed out in the Level Blueprint. If Save On Compile is not an option for the Level BP, it might be helpful to have a separate tooltip explaining why they're grayed out.

This is NOT a regression. Reproduced in 4.9.2 and 4.10.2 binary, and in 4.12 (Dev-Main at CL 2870013)

1. Open any project
2. Open the Level Blueprint
3. In the Toolbar, select the dropdown menu beside the Compile button
4. Hover over Save On Compile
