When I open the file, the column headings are missing. Excel shows them to be present.
Steps to Reproduce:
1.Open the file
2. Compare the results with excel
Column headers are missing.
Column headers present
User Profile Reset: No
I can provide the example file that you can see and/or screenshot of comparison of Excel/Calc
Created attachment 173635 [details]
Column headers not visible
This is the file that doesn't show headers.
Created attachment 173636 [details]
Shows the different views of the same file.
Created attachment 173639 [details]
Screenshot with the message error opening with excel
Seems there is same error in the file, like the error message opening with excel show. Excel it's able to recover it, while LibreOffice not.
Should be more a request for enhancement to recover files with error like this one.

Another observation: if I split the merged cells in A1:T2 or U1:BH2 then everything becomes visible in the third row that was somehow hidden, in:
Version: 126.96.36.199.beta1+ / LibreOffice Community
Build ID: 65dee56eed2111dfbe923ef82b3ba41a4c5edf75
CPU threads: 2; OS: Linux 4.15; UI render: default; VCL: gtk3
Locale: hu-HU (hu_HU.UTF-8); UI: en-US
But considering that both attachment 173636 [details] and attachment 173639 [details] shows this file is not valid according to Excel, I'd say this is a bug in the Apache POI generator or the way it was used.
Ok, let's close as notourbug
