BRO balance reduced while stacking

  • Dear Sirs,

    Some time ago I've received around 2000 BRO on my wallet and left it on-line for a week or so.

    I've checked each day the amount waiting for staking reward but nothing had happen until today.

    Today I realized my amount (in "balance" field) is reduced by one third!

    Same time the amount in "stake" field is increased by same value.

    Please clarify the situation. How this intended to work?

    Does this means I can still spend whole amount of BRO I possessed?

    Wallet "version" : "v1.0.0.1-61402", Linux.
