Hey I found a weird occurrence in my project that was not reproducible outside of the ecosystem of the project, however I was able to maintain the issue by locking the inputs before the join chop.
I have 2 chops on to the left of the join chop. the select chops show the contents of a specific channel for both A and B, before the join.
However after the join the values do not match the combination of A+B.
I think this is a bug, but maybe something else is going on?

Hi Lucas,
I notice you match the join by channel number, but the number of channels you are joining is not equal.
Null1 has 17 channels, and null1 has 18 channels. (it has a channel s which is missing in null1 - also channel order grb is different - not sure if that last part matters for you).
If I choose to match the join by channel name, the resulting last sample of RowID is indeed 7.
Oye! Rookie mistake.
Thanks for pointing that out. entirely user error. 
This thread is no longer relevant if anyone wants to get rid of it.
