Plug-ins thinks free space is "Free space: -878.96 % ( NaN undefined )"

hello, thanks
using axt1800, v4.0.0

so the free space is not correct?
Free space: -878.96 % ( NaN undefined )

Interesting. Maybe upgrade and test 4.0.1

perhaps has something to do with extroot

i am still confused, is v4.0.1 beta or stable?

at this point, as the router is my main home router, not able to run beta

Pls hold on a few days. Still workingon v4.0.1
