SMA of SMA return NAN sometimes even though there are enough bars

I have the following code for my chart

xa = stddev(close, 10);
xar = sma(xa, 30) / xa;
ratio=sma(xar, 40);
Plot(xa, "xa", colorBlue);
Plot(xar, "xar", colorGreen);
Plot(ratio, "ratio");

xa, xar are non-zero, but ratio shows NAN for the current bar for some charts even though the chart has more than 4000 data points.
One example is SIVB. Any idea what may be going on?

The ratio is plotted correctly. It is only NAN for the first 77 bars.
Please check that your data is correct.
If you still see issues, please contact support with a screenshot.
