The next day...
Because it was unusual I tried it twice yesterday with a human partner and the 'controlled by host' setting and the same thing happened both times.
Today - with a robot sitting North - it provides the expected alert when I hover over 2 and then the ♦ symbol viz., Jacoby transfer -- 5+ ♥.
Very strange.
