Cantina battle 8-G doesn't give Zeta rewards

It’s a very low drop rate.  Since the update I’ve received 10 Omega and 3 Zeta farming flawed signal data from this node.  Pretty happy with that drop rate for me.  It seems significantly improved from what it was.  

The Zetas and Omis in Cantina have a stupid low drop rate. I run all my energy on 9-f and maybe have had 1 Omi drop and before that when we just had 8 tiers I think over many years I had maybe 5 omis drop

I have only received 1 zeta from it out of all the energy I have used on it. But it does give them out eventually.
