You included the new logo in the resources.zip that you uploaded as well? It's possible to change the XML without uploading the new resources zip which is critical. If you're not seeing the logo on all reports (including out of the box like WOPRINT) then the issue definitely seems with the import.
If you're not seeing it on some reports then someone modified the reports to not inherit from Maximo and you have to modify the report. I've seen some people not understand how Maximo manages the template and embed logos into reports specifically.
