Shares Per Second at Zero in API when miners are hashing
I've got a MiningCore installation with LTC running. All seems to be working fine, but for some reason, the "Pool" Shares per second is at Zero, even though you can see the two connected miners are hashing and each have their own Share Per Second information being displayed. You can view the API live here: http://104.248.220.92:4000/api/pools/ltc1

Or look at the attached JPEG file

Why is the pool counting Zero as the Shares Per Second?

Is there a possibility that the Shares Per Second needs to collectively be above "1.0" for the software to count it?
