ssh terminal command result different

Hi,

I open multiple SSH terminal to manage cisco switch, but I got different display of result when I open multi entries at same time for same command:
First window shows everything correct
But 2nd tab of window, it has extra space line compare with first window for same command, the command stop display only for 2 lines, then I need press enter to get more info, this is something abnormal compare with normal cisco command output. Can you advise on this?

If open sessions one by one seems have no this issue, only happened with open multi session at one time.
