I am trying to resolve an issue regarding the imported docx files from word office 365 to the redhat linux server that uses LO for conversion of these docx files. The issue is that when opening the file, the header and some formatting regarding the fonts and other styles disappear in the newer versions of LO. For example the logo in the header is rendered but now shown and is malpositioned in the middle of the header and some texts also. These headers follow a template at the org. and does not seem to have problem with the earlier versions of LO (v6.4) when opened and converted to pdf.
Is this a known issue? What should I do? manually fixing the header is out of question since there could be thousands of files.
