I'm pretty sure Mark.I is named so in accordance with the original spelling that the dev adopted for w/e reason. Same goes for the inconsistency with Mk.II

As for Kouhyouteki, apparently it's because the dev omitted the A for w/e reason. You can actually verify this by checking them up in the equipment list. The A is omitted in the list and expanded again once you've selected it.

Anyone that's against it can run a petition to name equipment according to their image instead of their given name. As long as it's standardized I don't see the issue of choosing one over the other.
