Made a post with two pics about groups IT DISAPPEARD?

Hi I did a whole posting about how to deal with copies of groups in SKU
It simple dissappeared. Can’t find a trace of it

and I was wondering if I copy groups ( as per left) to export one by one to UE5
do I have to group them in SKU or delete etc I am at a loss.

These were the two pics attached
the problem when I export with datasmith I never get any file type
the goes into the name of the file

You mean this one?

It’s still here.

Hello Yes thank you.
mmm it did not show up on top right
maybe because there was no reply to it

Thank you anyways.
