  • Abdul , also let us know did you do a fresh install of Sites 9.5 or you did a upgrade from older version

  • Abdul , may be you have uploaded a wrong file , can you try to uplaod the file again and select the file type manually and see when you try to add the MM to the component it will save properly. the MM field is part of meta data.
