SendKeys to textbox throws errors

I have a test that fills out a billing form where you have textboxes and listboxes (to select the state). I am using Selenium/Java and using SauceLabs. When sending keys to the textboxes everything works fine but as soon as I select the state from the listbox, all of the previous already filled textboxes, an error message appears “This field is required” for each and every string box that was already filled. I spoke with Sauce and they have no idea why it is acting that way and think it is a bug with Appium
