I'm guessing you don't really know if it has grown?
Right now, you can't read the sizes of that recovery folder or tell what is in it.
I'd probably download WinDirStat to get a better look at what is in that partition.
As far as I know, that partition will still function as advertised even though you have the red flag.
You could probably add to it, but that would not resolve the issue of why a red flag all of a sudden.
To the extent you are willing to forego ever restoring to factory specs, you don't need that partition. When in doubt, keep it.
