It's case-sensitive. No, it's more broken (and it used to work with db all lowercase). I think the "db" in either casing makes it stop parsing and hence drop the +, too, setting it to 3 absolute no matter whether you have +, - or db or dB. The % options seems to work, but they would not provide a useful (even) increment over the range like a db setting would without first getting the current setting and doing some math yourself.
