Just a thought.
If it was there prior to you commencing and it's not a stain, which from your description it doesn't sound like it is, then it may be "Pile Reversal"
You most likely already know this info (but just in case) If it is "Pile Reversal" it's a phenomenon that occurs randomly in carpet and there is nothing you or anyone else can do about it unfortunately. There is no fix for it and no-one even knows why it occurs.
If it was only there after you cleaned then I don't know the answer to that one. Maybe Rick or one of the other fellows will be able to help.
