Terminals opening in new tab instead of same window

[vnktsh]

OS: Mac OSX Mojave 10.14.6

CSSHX:

brew install csshx
csshx -v
csshX  0.74

Example command executing on default Mac Terminal.app

csshx --ssh_args '-i ~/.ssh/key.pem' --login ubuntu 10.104.96.155 10.104.96.186

csshx --ssh_args '-i ~/.ssh/key.pem' --login ubuntu -x 1 -y 3 10.104.96.155 10.104.96.186

Opens each host in new tab, instead of tiling in same window.

Expected Behavior:
Each host window should be opened in the same parent window with red color terminal on the bottom.

You need to change the "prefer tab" setting from system preferences.
