Text disappears in text-box input

[unholy]

Hello.

I am trying to input some text in textbox using this code:

ControlSetText($hWnd, "", "[CLASS:TFidProfileDropDownNationality; INSTANCE:1]", "some text")

Interestingly when I move to the next line of code and try to set text to another text the text dissapears as if it did not exist at all

Also tried with ControlSend but still

$idFirstName = "[CLASS:TFidProfileEditFirstName; INSTANCE:1]"

;ControlFocus($hIndPflWnd, "", $idFirstName)
Sleep(100)
ControlSend($hIndPflWnd, "", $idFirstName, "Kricket")
Sleep(100)

Give me some ideas how to workaround this problem

Please see the video in attachment

without seeing the rest of the script it is hard to tell what is happening after the text is set.
