3.23 standard ssf ruthless atlas bonus issue

As the start of the new patch, i have completed a legacy t14 rare corrupted map first and gained most of my bonuses back.
After that i have completed another legacy map which was a t16 this time, and it gave me only a single completion point.
I expected a fully completed atlas, or up to t15 maybe.

I have one more legacy t16 and a legacy t15 as well. I dont want to waste them for a single bonus, because i had my atlas fully completed before.

Could you help me understand why was it not fully completed at my first t16 legacy map completion and what should i do next?

probably found the issue, my legacy map was converted to current league t16 when i corrupted it. the other t16 worked just fine
