Issue pulling S1701 in 2014 - 2018 5 Year Estimate Subject Tables

I'm trying to pull S1701_C02_042E and S1701_C03_042E from the 2014 - 2018 5 year estimates, however the values returned are -888888888. Are these data not calculated? S1701_C01_042E does return a value, but it's not quite the value I'm after as that's from Estimate!!Total vs Estimate!!Below Poverty Level. Is anyone else encountering this issue with their subject tables of interest?
