Contract Coin failed to track a contract

So since the Gun Mettle update rolled out, I have completed four different contracts, three of them for specific classes and one for a specific Gun Mettle map. Although, something isn't quite right.

Even though I have completed four contracts, my Contract Coin shows the stats from only three of them.

So is this just a weird bug? Can this be fixed?

The 2015 July 15 update (yesterday's update) included this in its patch notes:

• Fixed a case where Campaign Coins weren't displaying the correct stats based on the number of submitted contracts
  • Everyone affected by this bug has received the maximum contract points (including bonus points) for the missing contracts

So yes, it was a bug.
