In general, if you use an omnibus test, such as an ANOVA F-test or a Kruskal-Wallis H-test, it is illogical and poor practice to conduct pairwise comparisons when you fail to reject the null hypothesis on the omnibus test. Conducting the comparisons flies in the face of the omnibus: insufficient evidence to conclude differences does not warrant further investigation, as a general rule.
Usually, I would say report analyses you run, but in this case (which is different from selective reporting), the post-hoc p-values are inappropriate to interpret and should be omitted. The omnibus p-value is appropriate since this is the “gatekeeper” test.
