[Geany] problem with systax highlighting

Hello, geany community.

I have installed the latest version of Geany (1.22). And there a problem or maybe inconvenience with the highlighting I chose for strings.

In filetypes.common (that I copied from /usr/share/geany to my home config folder) I defined color for strings like that

string=0x000000;0xffc0c0

This is black font on pink background. Well, I like not to highlight the font itself but rather background of specific tokens.

So, the result (in PHP) is like this

BUT, at the same time all the white space of other types of files BECOMES PINK

For example, the file filetypes.common itself is like this

This is wrong, isn't it?
