They have a good point for it being theirs: they're owed that exact amount by Revlon. From their point of view, somebody at Revlon figured "let's just pay them in full" and a few days later somebody else thought "that wasn't a good idea, let's get the money back". If it was e.g. the expected amount with one or two additional zeros, that might point to a typo. But the exact amount of $176.2mn instead of $1.5mn? That may still be a mistake, but it's not that obvious.
