Originally Fidelity Cash Management accounts were setup as bank accounts and grouped with other bank accounts in your dashboard. While these accounts may be primarily cash accounts, they are able to be used for trading and are not traditional "bank" accounts.
Based on recommendations from Fidelity, we have made a change to group these accounts with your investment accounts. This change is in line with the classification of these accounts at the Fidelity site, and you will now see all of your Fidelity accounts under investments (excluding any Fidelity Visa accounts).
