Lightspeed Tokens Eat Character Shards

It seems that lightspeed tokens will consume already obtained character shards of whatever character you upgrade. Example: Batcher.

We get 98 shards of Batcher this month. If you use the Episode track's bronzium Bad Batch LST on Batcher, you will still get the character but it consumed 80 of your shards leaving you with 18 shards. I know this because it happened to me just now (Pictures attached).

Im not terribely upset about batcher, but what I did spent money on mega chase bundles as i thought i could use aurodium LSTs on those mega chase characters, use my bought shards to upgrade to 7 stars. Instead i have basically spent money on nothing. This restriction is not mentioned anywhere in-game. Truthfully, i don't want a refund, i want this bug (Or design choice) changed so that i can basically pre-farm last character shards i need for my future lsts.
