dfw ch 8 changes to abc 13 in oklahoma

[lancaster6]

Hi. I have a very strange problem. I'm using nextpvr to pull ota channels through hauppauge tuners. On my main PC, it works fine. I really want it on my intel nuc running win10, so I have it installed there as well. On the nuc, it sets up and works fine. I come back later and a few channels are showing out of market feeds. The guide doesn't change, just the channel feed. One example is channel 8, abc in DFW. It changes to 13 Oklahoma. This only hapopens on the Nuc, the main PC stays solid. 
    Thx for any advice.
