They appear to share the same value.
Give your devil skill another number, and it gets fixed magically (both, client and server sided).

Devil Spirit Skill: 1234567
Change the figure of your devil spirit to: 1234568 - fixed.
About your holy spell thing, you seem to use another "debuff-protective" skill, or the same issue here, regarding Basic_ChainCode.
