Usually any TODO items show up in my Global TODO list as eg:

[Filename of org file] TODO Buy milk

I had copied some headings from another org mode file into the current org mode file and now the Global TODO list shows the same heading as:

[Filename of org file] file:TODO Buy milk

And the TODO is no longer in bold and does not have the same color as before.

I assume by copying over heading from another file into current file, I corrupted the current file somehow. But I dont know how I might have done that.

Any help on this is very much appreciated.

Also, I tried to search for any ways to check an org mode file for corruption but did not find anything. Is there any way to do this?

Thanks ahead of time.

Edit: org-lint discovered an extra line of text between heading and SCHEDULED line
