Moving of the enemy should not be done in render, but instead in update. It should be in the update method of the Enemy class.

// Move enemy sprite
            for (int i = 0; i < spawnedEnemySprites.size(); i++) {
                if(gameState.getEnemies().get(i).isActive()){
                    spawnedEnemySprites.get(i).setX(gameState.getEnemies().get(i).getX());
                    spawnedEnemySprites.get(i).setY(gameState.getEnemies().get(i).getY());
                    spawnedEnemySprites.get(i).setRotation(gameState.getEnemies().get(i).getAngle());
                    spawnedEnemySprites.get(i).draw(spriteBatch);
                }
            }
