Any chance you can combine your two posts here? Double posting is considered a violation of the rules around here; I've even seen posts of mine merged despite posting them over 24 hours (like, several days) apart just because of the letter of the rule, which in turn makes the last reply to the thread looks older than it is.
I agree with MIAU, BTW; check the Ditto and other parent at the Daycare just to be sure. I actually had once put two parents in the Daycare for something (no Ditto) and actually mislabeled the IVs; the clue was exactly what you described, with one stat always missing. It doesn't hurt to check it. :) This is a Florges, BTW? I have all five colours with various spreads (all 5IV), so I might be able to help with that if you still aren't lucky.
