Strange behvior in Application Rules for firewall?

[desmond_z]

I run an english language version of Windows 10, and have used Avast for many years.
When I recently looked in Avast's firewall, then scrolled down to System, I notice that the info changes at times. Most other Apps/programs show where it is installed, except the System.
System shows 2 different strings of what looks like Japanese text. See attached pics.
1) This is what I first saw https://gyazo.com/94f339718859cbd56aeea3dda187c1a3

2) After deleting a rule for a removed app, I now get this https://gyazo.com/17b2850d23f3a5708ca9da23d5867a71

Is this normal behavior or should I investigate further?
