Britain's Lauren Williams and Peter Longobardi-Radford missed out on medals after losing in the World Championships quarter-finals in South Korea.
Williams, 18, led with just 10 seconds remaining, but a ferocious late attack by opponent Mengyu Zhang saw the Chinese fighter win 31-22.
Longobardi-Radford, who has previously competed for Spain, lost 24-10 to Yu-Jen Huang.
"I just didn't get my tactics right," he told BBC Sport.
Victory in the quarter-finals would have guaranteed the British fighters a medal.
Williams, a double world junior champion and senior European gold medallist, opened her day with a dominant 29-7 defeat of Ivory Coast fighter Marie Federique Ekpitini.
The seventh seed followed that up with a tense sudden-death, golden-point success over Athanasia Mitsopoulou of Greece, before a concentration lapse saw her eliminated in the next round.
Longobardi-Radford, who had won all five lower-ranking events he entered since joining the Great Britain programme in 2016, opened with a 18-11 preliminary round defeat of Turkey's Ferhat Can Kavurat.
Emphatic defeats of Moroccan fighter Faical Saidi (19-4) and Arven Al Cantara of the Philippines (22-8) followed before he was outclassed by Huang of Chinese Taipei.
"For sure I'm happy with what I've achieved recently, but today wasn't the performance I was looking for and that's a disappointment," he said.
Defending +73kg champion Bianca Walkden, who two years ago became only Britain's second World Taekwondo gold medallist, begins her campaign for a further title on Tuesday.
Fellow Team GB Rio Olympic medallists Lutalo Muhammad and Jade Jones begin their quests for their first world titles on Wednesday and Thursday respectively.
