You are not alone with this. Me and my clanmate also have this new bug. Clicking a specific graviton will use up 2 or all of the same type from your bar, even other types might also vanish

like it happened with me when i decided to record it and send in a ticket.
This was 10 days ago, i got as a reply that it will be investigated. Since then it happened again, i just hope they find the cause and will fix it soon.
You guys should also send a bug ticket, with more information maybe it will be solved faster.
