Upon loading wallets from a seed phrase, I added about 10 from the derived addresses in the 'Add Account' side bar.
One wallet I did not want to include in the accounts, so I clicked into wallet, and clicked into it on main sidebar, went into 'Account Settings' and clicked 'Remove this Account'
at this point the entire sidebar went black and no wallets accounts were visible.
Had to quit and restart app, which resolved the issue and the desired accounts were displayed correctly
