FYI, the problem was caused by the "name-suggestion-index" package.  This package contains a list of brands, which the iD editor uses to suggest "fixes" whenever a user clicks on an object.
"Blue-bike" is the correct spelling.
We also spotted the issue and had it fixed in August.  From now on, iD users will not be prompted to rename them into Blue-Bike.
