JOSM negated regular expression match, question.

JOSM MAPCSS

When I use a code:

[lanes!~/1|2|3|4|5|6|7/]::highway_lanes_layer

to exclude: negated ​Regular expression match, all others should get a "else" icon Then I have a lanes=10 on a way. This 10 should get a "else" icon, This icon is not showing, because 10 has number 1 in 10, the program can not choose. Also lanes=1 icon is not showing. If I have lanes=8 or lanes=9, I get the "else" icon.

What am I doing wrong.
