Hi,
I found this bug in relativity 6.x-1.x-dev, but didn't try it on d5 version :
If you use an underscore in your chlidren Content-Type Type, when you click on "create children CT" link, you go to main Content Creation page and have to choose your CT. So relationship is not setup.
I spent a lot of time before finding this problem reason, so I hope it may help.

jonhattanalready fixed in #251802: When a type has an underscore, its nodes can't be set as children on creation
