Hm, this is getting hard to answer. Adding normal instances of ZCLasses
to other ZClasses should work. Are you adding everything straight from
the management interface or programmatically from DTML? 
If from the management interface, are you sure you always add TinyTable
etc from within the instance?
If programmatically, could you send the code?

Perhaps you could try and adding one of the problem products in another
way (from a dtml method instead of the management interface or the other
way around).
