Compressor Settings not Updated ??

Correct me if I'm wrong but it seems that changing the settings of a Compressor preset in Compressor doesn't update the said preset in the list of FCPX's Share>"Destinations". I have to exclude this preset and reintroduce it in the list to get it right. If so, that's as unexpected as unfortunate... Please can anyone check this on their side (of course you'll have to export 2 files to compare).

Thank you very much.
