Binding issues 4.6c

[Rick Sample]

Yes. I did refresh the buffers. (First thing I do before I run my consistency checks after transport to HQ0.)
I also created a new version in HD0 before I made changes for the new transport..
 
================================================================
I have a binding issue every once and a while. Here is the what I happens. 
 
For one WF in HD0, I have TYPEID SOS04.L_ART that does not show in the WF Template container. 
When I go to the workflow builder, it is there. Everything works fine. (WF works, no errors in consistency check, etc.)
 
When I transport to HQ0, I get binding errors! TYPEID is nowhere to be found and binging errors 
between WF Def and Tasks.
 
I am not sure why this happens. Also, every once and a while I loose containers in the WF Template. 
They are in the Tasks and Template on HD0 but get "lost" in the transport! 
 
I don't see a pattern or anything I am doing wrong. The only way I have been able to fix this 
in the past is to Add the containers in question to the WF Template and transport again. 
Annoying!
 
I need to be able to explain this other in shop as to why.
OSS note on this issue?
