Hi [Xingchen [Content removed]
Thank you for reporting this issue. This seems to be related to the known issue UE-252268, which was reported for UE 5.5 and fixed for UE 5.6, but I was able to repro it on the latest version, so we will treat it as a new issue. Note that, to see the correct actor label on the outliner after that operation, you can simply press F5 to refresh it.
I have filed a new internal bug report for this. You will be able to track progress on it here once the engine devs mark it as public: UE-303041.
Best regards,
Vitor
