Darth Revan Journey Missing Shards

Greetings everybody and happy holidays.  

I have completed the Darth revan journey and i am missing 55 shards. One mission crashed so i didn't get the rewards from it. I tried playing the event again but no rewards. 

I am playing on PC through the EA Play App

Any help would be appreciated .

My ally code is 344-654-819

Below is a screenshot for proof that i completed the event and have not aquired all shards.

Thank you in advance.
