Hello,
It looks like it is related to the data.
Initially when you designed your document, did you capture the data the same way you are doing it within PPressWatch?
If the data wasn't captured the same way, you may now have a different format such as having extra lines or characters at the beginning of the data file, etc.
I guess, you should have a closer look at the data file and see the difference between what you designed your document with versus what you have now.
You may also consider opening an issue with us and provide your document, your old data file and the new data file.
Have yourself a wonderful Holiday!
