How to use Randomizer Tool on Surface Instancer?

Hello Omniverse devs!

Please see this video, its alembic file imported to Composer ( saved as new USD ) and duplicated to plane with Surface Instancer, then I try to randomize the position and most important - the rotation.

But as you can see, I do not manage to get any variation or randomization on rotation, but this tool is supposed to do it. What am I doing wrong.

Also, how can I make randomization on time value, so they would not play back 100% synchronized but each at different time?


The only way I found out was by manually duplicating my usd assets and lay them out in seq timeline and then use Randomizer to move & rotate them:
