Found out that I have been mining for hours and hours while my unpaid balance is not increasing... Something wrong?

See attached image, first arrow I started mining on wallet with 3x GTX 1080 ti, balance is increasing until there was a payout. After payout small incline and at second arrow there is no increase anymore. Earnings are not showing up. Its mining nist5 for long time.

AFTER SOME MORE RESEARCH, ITS SEEMS THERE IS A CHAINSPLIT FOR BULWARK COIN ON NIST5, SEE BELOW ANNOUNCEMENT

Announcement: [2018-02-04 22:49 UTC] Please do not use 24 hour actuals in your profit switching script. When chain split happens, the pool will disable coins, or even disable the entire algo, and if you are using the past 24 hours actuals algo profit ranking to pick algo, you will be wasting your hash power. Bul wark just had a chain split, we disabled Bulwark but there are still 700+ miners on Nist5 after an hour, this tells us at least 700 rigs are doing it wrong. You should only use current estimates in determining your algo. And if you don't want it to switch too often, just increase the interval time. Do NOT use 24 hours actuals.
