Hide Pinegrow application via keyboard (command-H) not working on my Mac

I have to go manually to the top menu to Hide Pinegrow, since using my keyboard doesn’t hide the app. macOS 10.14.6 Mojave/27" iMac. Is there a system settings change or fix for this?

No one else is having this issue? I don’t see a workaround, and it is pretty annoying, having to switch between apps all the time. I have noticed that if I have something active open in PG, such as if I go: File > New page, then command-hide works via the command-H on the keyboard. But not unless some other window is active.

In normal mode command-H seems to be opening up the EDIT CODE window.
