About a week ago, I started receiving an error on one of my Fidelity accounts. When I validate and repair, it shows Maximum security reference: 173, number of securities: 173. According to everything I've seen on the forum, some say the Maximum number is 255 and some say it's 2000, regardless, not close to the 173 that I have. How do I increase the Maximum number of Securities or what else can be done to correct the error?
