Unclear meaning of "number of lanes has fixed according number of turns"

[holgersoft]

In TurnLanesEditorDialog.java line 253 is the notification " The number of lanes has fixed according number of turns". What is the purpose of the notification? Is it to tell the user that something is wrong? What is the user supposed to do with the information? What means "fixed"? Is that a defined number, how big is it? I try to translate the notification in Launchpad (where all JOSM strings are translated), but I'm not sure what the message is. My guess is something like "The number of lanes (key 'lanes') does not match the number of turns (key 'turn:lanes')", but I might be wrong. Please rephrase the notification (and the other four of the same type) if possible.

Please remove the space at the beginning of the notification.

Or does it mean "The number of lanes was changed based on the number of turns"?
