SendKeys misses some characters

Appium Version : v1.13.0-beta.1
IOS version : 11.0
Automation name : XCUITest

I am automating a native page from a hybrid IOS application. For the test, I have to enter an amount “0.05” to one of the native fields, for which I am using sendkeys. The issue now is that randomly, certain keys gets missed and the script ends up entering wrong amounts to the field like “005” etc . Could you please advice?
