I have 3-4 coins wallet , but some wallets are good but some have problems frequently its affecting my staking rewards
what do you mean by staking in one computer with several wallets? with the same coin if like that it's impossible as far as I know, staking is only used by one wallet, one coin on one device maybe that's why it doesn't work all. for more details you ask the dev coin because you didn't mention name your coin.
unless there is activating masternode, the result may be different, and in my opinion the reward for staking is not much.
