Default filter regexes have errors in Godot 3.1

[youreperfect]

Console shows: modules/regex/regex.cpp:218 - 14: missing closing parenthesis
and the filter item shows these red exclamation points.

changing them does fix the red exclamation point problem. For example:

[youreperfect]

Update - it appears that if you quit Godot when you start it again the filters all show errors but if you add a whitespace and remov it then it shows as correct
