This "improved" FT indexing system has caused this very problem since April 2009.

On 4/21/2009, I raised this exact same question (re: profile mismatch. Please read post#133 and beyond) but I don't think IB ever works on nor addresses this issue. At least I've never heard anything from IB, both publicly and privately, w/r/t this annoying problem.

Not sure if it's a (technical) problem with no fix as far as FT goes.
