Cant open two terminal windows in elementary

I am currently using Elementary OS. Some while back I could open up more than one terminal just by "Win+T" but now I just cant. The first terminal opens up without a hitch. However the second one just does not show up no matter what I do. Anyone knows how to fix this?
P.S. the terminal command being used is "io.elementary.terminal".

Solution

Default shortcut to open terminal is Ctrl-Alt-T. I had the same issue after some unknows update on my machine. I fixed this by disabling System terminal shortcut and added custom shortcut.

The command that is used to fix this is io.elementary.terminal -n The -n flag stands for new window.

Edit: i got this problem when i switched from bash to zsh.
