SharePoint Library move action changes content type to folder

Question

I am using a content type as an active case-file. When that case-file is closed, a flow moves the file to a Closed library with the same Content Type. For the previous three years, no issues. Suddenly in 2022 some, but not all, of the closed case-files are having their content type changed to Folder in the Closed library. Any ideas on why this is suddenly happening when nothing has changed on my end, in my flow or in my content type?

Hi RyanCooney：

We are very sorry for the inconvenience this issue has caused you. According to your description, my understanding is that when you use Flow to move the file, the content type has changed. Is my understanding correct? If my understanding is incorrect, please feel free to correct me..

For better testing and investigation, could you please provide a screenshot of your content type, in my test, the case-file type was not found：

Also, we would like to know if this issue still occurs if you move manually without using Flow.

Thank you for taking the time to fix this with us。

Best regards,

Tin
