Wave offset ignoring Y axis changes

I'm not sure if I can send this as a bug given certain reason but I've noticed that in multiple instances when using the Triggered Spawner and the wave offset option. The spawner is not taking the y axis number into account. It works when I make a new project so I'm not sure if it's a issue with another asset or something that I'm inputting wrong within the settings for the Triggered Spawner.

Is there any reason why the y axis would be ignored by the triggered spawner? I can't seem to find any obvious reasons so I'm curious if other assets can cause this issue.
