TotalFinder deletes from wrong Finder window

TotalFinder 1.6.27 on OS X 10.10.3

I verified this is repeatable.

Started with a single Finder window with two tabs, then dragged one of the tabs out to end up with two windows. I clicked on the new window to bring it forward, selected a folder to delete, then used cmd-Delete to delete it. Unfortunately, what’s deleted is the item selected in the other window. Even though that’s not the active window, the selection remains active and is deleted with the keyboard command. This doesn’t happen when using the context menu to trash the file. It also doesn’t happen if I touch a different Finder window and come back to the original two.

Any suggestions?
