iTerm2 opens tab with different profile than the default

I have a specific profile set as my default in iTerm2. For some weird reason, when I open a new tab using the Shell > New Tab menu item, iTerm2 opens the tab with the correct profile. I get the same profile when I open a new window. When you open the Shell menue and look at the New Tab entry in it, does it display ⌘ T But when I use the keyboard shortcut ⌘ T, it opens using a different profile. I've checked my macOS system keyboard shortcuts, and there's nothing for this shortcut in there. I'm on macOS Sequoia and zsh.
