Textbox values disappear after adding Year value from Date Picker
I'm testing on an Electron-based Desktop application, in which I'm trying to create a new order. When I run the keyword test for automation with excel sheet as the data being inputted, the 3 textbox that I have each gets properly filled up with the text from the excel file, but when it reaches the dateInputStartDate, entering the date makes the values from the 3 previous textbox disappear. I've been trying to fix this by changing the values of the date to string, putting quotations, and just having something like "05152024" instead of 05/15/2024. What's also weird is that when TestComplete enters the day and the month, it doesn't make the values in the 3 textbox disappear, but when it gets to the year portion, that's where the problem arises.
Any idea of how to go about this next?
