Spreedsheeds always loses header and footer when reopened

I´m using LibreOffice to design .odt spreadsheets. I setup a header and footer formats. When I close (and save) the document and open it again the header and footer are disabled. So I need to manually enter on Page Style and enable they again (the format are not losed). It always occurs in all the speadsheets.

What I am doing wrong ?

An already reported bug. Bug 144940 - Calc disables header/footer or looses footer content when saves a spreadsheet ( part 2 )
