This topic is more elaborate than I thought at the beginning of my adventure with TestComplete.

If these threads do not help you, I can help you.

As Wamboo , this is a common issue that stems from inaccurate mapping of objects.  Read through the articles but I'd also recommend going through the documentation topics on NameMapping. (https://support.smartbear.com/testcomplete/docs/testing-with/object-identification/name-mapping/about.html)

There is also a brief tutorial video on the issue.  It's based off an older version of TestComplete but the concept is still relevant.
