Clear blue BFP, FRER BFN?

First test, bfp on a pregmate (ignore the ovulation strip package lol I was testing the theory of dark LH strip = pregnant)

Second test was BFN on FRER

Third test was BFP on clear blue digi. Anyone else had this? All were dipped in the same cup of pee, after a 6 hour hold at 9dpo.
