2D Java Game Programming Animation Issue -

i'm working on swimming animation. when player collides watertile, swimming animation not play when player goes left (lt) , when player goes right (rt), animation plays.

here render method player.java: -edited-

if (isswimming){         if (up) {             swimup.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }          if (dn){             swimdown.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }         if (rt){             swimright.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }         if (lt){             swimleft.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }     }         if (!isswimming){         if(up){             upanimation.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }          if (dn){             downanimation.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }         if (rt){             rightanimation.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         }         if (lt){             leftanimation.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);         } else             idle.render(g, x, y, game.tilesize * game.scale, game.tilesize * game.scale);  } 

also, may worth noting there no errors being displayed.
