[求助] 使用 sendkeys 方法发送文本时会出现重复输入的情况

各位大神们，本人刚刚入门自学移动端自动化测试，在编写代码过程中出现标题所述问题，一直找不到解决方法，请求各位大神帮助
测试环境应用
appium版本 1.4.16.1
系统：Win7X64
jar包版本：java-client-4.0.0，selenium-java-2.53.0
安卓模拟器为Nexus 5 ，安卓版本为5.1.1，API 22
使用JAVA语言，首先设置默认键盘已经设置
capabilities.setCapability("unicodeKeyboard", "True");
capabilities.setCapability("resetKeyboard", "True");
输入语句如下，其中driver定义的是AndroidDriver
driver.findElementById("com.ccz.insure:id/et_car_owner_id_number").clear();
driver.findElementById("com.ccz.insure:id/et_car_owner_id_number").sendKeys("510623198408133813");
我将以上语句转换成web后实验也不行，log信息如下，发送的510623198408133813，在APP上面显示出来的是551062311988408138813
