What version of GWS are you using if you are using the v188.8.131.52 uninstall it and go back to v2.0.0 the update has more headaches than it is worth.
Reboot after you reinstall v2.0.0
If they are not back please let me know if they are available on a new project. But I’m pretty sure they will be back.
If you are using a Mac there are hoops to go through to run v2.0.0
