You are getting a p-value, namely p=0. It's just that, when taken literally, the p-values are wrong.
I'm not familiar with predictABEL, but my guess is that the p-value is below 2e-16 or some such cutoff and gets printed as zero (the means seem to be about 10 standard deviations away from zero, which would give a p-value of 1e-24, plus or minus a few orders of magnitude). You may want to ask the maintainer of predictABEL what the lowest printed p-value is (say 1e-15), then change the p=0 values to "less than 1e-15".
