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.
