I think these are probably configurable, right? In any case, if I use them, it works fine in Agenda, but maybe I am not using those Spaces shortcuts.
In any case, you should be able to change Agenda’s shortcuts in System Settings. If you want to use the Spaces ones, you could either change those, or change the ones for Agenda.
There are limited logical options for shortcuts, which means you can get collisions. I noticed that my ChatGPT key combo was colliding with Quick Open in Agenda, for example. Don’t think you have much choice but to change one of them.
