Ok Folks, so i think i figured this out.
It appears that Tealium Dev, missed the checkout_step in the 'checkout_progress' event. So added this into the tag template and it works a charm.
Also note, for anyone migrating to gtag.js, that firing the 'begin_checkout' event autoamtically sets checkout_step = 1.
