This is caused by the difference in spool files MVSSPL02.dat (used by websync 8 and later) as opposed to the MVSSPL01.dat used by previous websyncs of MFE 3.1. This can occur when templates for older websync are applied to newer websync projects. If MVSSPL01.dat exists alongside with MVSSPL02.dat it will need to be renamed or deleted.When the new version mvsspl02.dat is created the mvsspl01.dat's information should be stored in mvsspl01.r1.
Therefore you can delete the mvsspl01.dat file from the projects.

To display the old version of the spool ( the mvsspl01.r1 ) the easiest way would be to make a copy of your project and in the copied version of your project, delete the mvsspl02.dat and rename the mvsspl01.d1 back to mvsspl01.dat.Then when you open the spool in this new copy of the project it will redo the conversion and create a new mvsspl02.dat from mvsspl01.dat. This can then be viewed in the spool display.

If you have a machine with the old version of MFE then the new copy of the project will display the mvsspl01.dat without doing the reformatting.
