GetTextLocation method is not working properly

I am searching a word "DR" withing a Winobjetc by using the below given code;

Window("Job Console").Activate
strFind=Window("Job Console").WinObject("WindowsForms10.Window.8.app.0.").GetTextLocation("DR",l,t,r,b)
If strFind=True Then
msgbox "Coordinates are:"& l & "," & t & "," & r & "," & b
Window("Job Console").WinObject("WindowsForms10.Window.8.app.0.").Click (l+r)/2,(t+b)/2
End If
For search word "DR" , the co ordinates are giving as 0,0,787,389, now if I change the serach word to "DR01322552"( which is not present within the winobject) then also the coordinates are giving as 0,0,787,389.

Can anyone please help me to resolve this issue.
