Missing R2-D2 shards after passing the event

Hello everyone!

I passed the event on R2-D2 a couple of months ago, but didn't notice that I didn't get all the shards after passing the event.

Now I have 15/100, 85 shards are missing. It could be the 6th stage when I didn't get the shards.

Please solve this problem.
