You said your brew sat for two weeks; if one of those two weeks was for cold crashing, it's very possible your yeast hasn't finished fermentation. When you chill it down, the yeast stop doing their thing and fermentation stalls.
It's best to take gravity reading two days apart until you get identical readings. Then fermentation should be complete. I like to let my beer ferment for two weeks before taking the first FG reading and then take another two days later. If fermentation is finished, then I cold crash the brew and bottle it.
Personally, I'm not opposed to a bit of traub in the bottom of the bottle. If the brew has been stored in a fridge, then most of the traub stays in the bottom of the bottle anyway.
Good luck.
