The dialog walked a hand-written GROUPS array. "The contact" was added to the
fields and not to it, so mode, submode and RST existed, passed every check I had
written, and could not be picked — the same shape of fault as the missing column
mapping, one layer further out. Two lists that must agree, with nothing making
them agree.
GROUPS is derived from the fields now, in declaration order, so adding a group
is adding a field. A group with no translation falls back to its own name rather
than rendering an empty heading: a missing label should look untidy, not
invisible.
Also stacks the DX sunrise/sunset in the band-slot header. Side by side it cost
about 150 px of a row that also carries the callsign, the badges and the band
grid, and it was what pushed that row onto a second line. Two short times one
above the other cost a fraction of it and no extra height — the row is already
taller than one line of text. The "UTC" label goes to the tooltip: the times are
monospaced and always UTC everywhere in OpsLog, so it was spending width to
repeat a convention the operator already lives by.
