That why I think you wrongly initialize you db in the first place while
onboarding the record versioning feature...

Please try on your side to create new app drop the model and fixture I
include in one of my last email and start web2py shell and launch the
various commands of yours...

You should get the same output number of record...

If you don't it might happen that there was a bug in 2.15.4 web2py version
/ pyDAL...

Try new version...
