Under Window menu there are two (2!) entries with Effect&Presets. One is greyed out.

Sounds like something has gone awry with your install. I'd recommend uninstalling, running the Adobe CC Cleaner tool, and reinstalling.
I fixed it by myself. In some kind of way one of the user workspace has an error. Removed it, created new. Done.
It is a little bit frustrating that software support recomends you uninstall software package completelly as a repair solution. Imagine your doctor recomends you transplantation of all the internal organs because of some small difficulties to diagnose gastric ulcer.
Thanks for sharing what worked. Reinstalling, especially on CC, is actually a pretty quick and painless process these days so, for weird issues like this, it's often a good suggestion. I'm glad you found something even easier! Now I'll know to tell other folks to do that if anyone else pops in here (or if it happens to me).
