Additional information you deem important (e.g. issue happens only occasionally):
This looks identical to #32648 but as @schmichael notes that was fixed in 18.06.1-ce or earlier. This appears to be a new manifestation in 19.03.1 (or earlier?)

My mistake, I don't think this is version related after all. This is probably a dup of #26799. During first run post-install of either version I cited above, the Gateway field is missing. After a daemon restart or a reboot, it's present.
