The wallet has really an issue... I receive stake last time but I haven't seen the staking arrow showing green color, it just always says staking not active, multi-send not active
This is because none of your coins have a minimum stake age of 7 days. As soons as they reach 7 days old staking will turn green and you will get stakes until you run out of "old" coins again.
As soon as you run out of "old" coins you will loose staking status and the process begins again.
I have to say that the minimum 7 day age thing was a pretty bad decision by the devs, it has caused major confusion and problems.
