It may be important to notice that this "C3" note is also displayed where it's not supposed to and may be a cause in the original issue.

It's likely a layout issue (lr-tb) caused by a missing font (courier).

This issue also occurs in the case of this PDF. The whole table is being pushed down to the 2nd page.
It is unknown whether the same issue as the original PDF file causes this behavior so it will be separately addressed if that's the case.

This issue can also be observed on the attached PDF; All data is pushed down to the second page. The first page is blank. Let us know if you want us to log a separate report for it.
