My balance has been steadily increasing, but I've been using NemosMiner which switches between algos and your fragment of a screenshot suggests you've been on Lyra2v2 the entire time so any issue is likely with one of those coins. I've had good results single-algo mining lyra2v2 here before, but yesterday I noticed a similar problem as you when I tried mining Equihash for about 4 hours - no earned coins in that time so went back to NemosMiner (just trying to get my balance up then I am done with NemosMiner and the other algo-switching programs).
