Minor Bug Report
In Advanced Firecalc, when one selects the "How is it invested" tab, one can set the equity/fixed income % ratio.
If one tries to change one's mind and not accept the top default "Total Market, split" radio button, but rather choose one of the other radio buttons like "A mixed portfolio . . . " or "A portfolio with consistent . . . " or "A portfolio with variable . . ." the equity/fixed income % grays out (as it should since it no longer matters) -- but if you want to return to the top (default) radio button . . . the equity/fixed income % ratio never ungrays.
Once you leave that radio button, that ratio can't be changed without exiting the webpage and restarting. Probable bug.
