New tab and window inbound requests opening in new windows vs existing tabs in 10.13ß8

I’m seeing a problem in High Sierra where when I open new tabs via revealing in Finder and other such actions, new tabs are always being opened in new windows vs being opened in a tab within an existing TotalFinder window. Is there any way to force TotalFinder to open all inbound new tab/new window requests to open as a tab instead?
