When there are multiple xpaths(1,2,3,4,5) in the same object of the namemapping. Like your capture shown.
I think the check rule like below.
TestComplete will recognize the object with the order of the selected xpaths.
If 1 failed it will check 2. If 2 failed it will check 3....
If you want to recognize the object correctly.
1.Make sure the xpath is correct first.
2.Make sure the object display when you operate it by xpath.(You can add delay time in the previous step)
To the xpath:
You can try to replace start-with with contains.
I hope it can help.
