windows in mutli spaces in mac switch

hello, i use intellij CE 2018.1 in mac Sierra.

I create 2 spaces in mac, and open 2 intellij windows in each space. I know cmd+` will switch between windows, but intellij will switch between all opened windows all over the 2 spaces. I hope it only switch windows in the current space. 

Other apps in mac switch in current space. 

I've tried open intelliJ CE in one space and IntelliJ UE in another space, but cmd+` will switch between them too, they are 2 different app, i think it's not right.
