Legendary Selection Recruitment BUG!!??

We all know that we can pick any 3* from legendary scroll once we achieved 28 checked in based on cumulative attendance.
Unfortunately I didn't get any.
I have check my inventory bag as well as Hunter library and it's cleared that I didn't get any. I also check on the supply site and mailbox as well just in case but nothing received.
Anyone facing the same issue???
