Threads showing on new BB, is this a problem?

Just had a new FSA Isis Bottom Bracket and compact crankset installed..

As I look down I see about 1 1/2 threads showing on the non-drive side.. It doesn't appear to be coming undone but it is not flush like the drive side.. I have put about 50 miles on it so far..

Is this something that I should be concerned about, it is an Italian BB which are known for coming undone?

The drive side needs to be flush. The drive side needs to be properly tightened not to come undone. The non drive side snugs up against the end of the cartridge.It may or may not be flush.

THe non drive side does not necessarily need to be flush. BUt do check just in case, mine was not flush and i thought it was okay until one day i decided "hmm maybe i will tighten this a bit to check it out" and guess what, it went in quite a bit more.
