Krysten Coombs, Jack Shephard and Martin Rooke all fell to semi-final defeats at the Brazil Para-Badminton international.
In the men’s SH6 singles, Shephard was on the wrong side of a three-game marathon losing to home favourite Vitor Gonçalves Tavares.
Wins over Ireland’s Niall Mcveigh and Dheyvid Bisto De Almeida ensured the top seed progressed to the group stage.
While there was a straightforward 21-10 21-7 victory over Charles Noakes in the quarter-final but it was a trickier scenario in the final four.
After losing the first game 21-15, Shephard came back levelling the match by winning 21-18 but was agonisingly defeated 26-24 by Gonçalves Tavares in the final game.
Elsewhere in the SH6 singles, Coombs came through his group matches triumphing against Chen Yi-Ying, Luo Guangliang and Hector Jesus Salva Tunque with ease.
But Nagar Krishna proved too strong in the semi-finals and was able to edge out Coombs in both games winning 23-21, 21-18.
For Rooke in the men’s WH2 singles, the second seed made light work of the group stage beating Claudiomiro Segatto and Thomas Jakobs.
In the last eight, Rooke came through a tough contest against Zhao Xin after he beat him 18-21, 23-21, 21-13.
But in a pulsating semi-final, Rooke was unable to come through another three-game contest as he fell 21-18 20-22 21-17 against Israel’s Amir Levi.
