Hi Nova9,
I had the same issue and raised it with OS. They said Standard Application Reports PV6.4.0 SV100 is not compatible with Platform Version 9. OneStream recommends using Navigation Center, which comes packaged with Platform Version 9, for your reporting needs.
I downloaded and installed Navigation Center from Solution Exchange and then navigate to Narrative Reporting from Navigation Center in One Place rather than Standard Application Reports and it fixed that issue (although it created other issues with my header formatting in my books).
With regards to the charts/graphs.. I also have issues, they seem to disappear.
