Microsoft outlook 2011 many questions

[novax]

Hey, i am having some very annoying problems with MICROSOFT outlook 2010,
in the last month the following has happened:

in my contacts on outlook some of them have suddenly gotten a '-' in front of the names so eg if my name was John Paul
my name is now -John Paul
and this has make the alphabetical order of my contacts all messed up, when i go into the contacts area is does not show the '-' it still says John Paul, then once i hit save and exit, suddenly its gone and its no longer got '-' but its no longer under 'J' or 'P' i don't even know where its gone unless i search for it!
also:
its deleting parts of peoples names randomly, for eg if my name was John Jack Paul



now the contact is either Jack Paul
or
John Jack
i have no idea why this has happened, i have over 6000+ contacts so its hard to keep track of which ones are broken and which ones are still normal.


ALSO

In my work whenever i send an email to a costumer we are asked to send our email to our sales team as well, so when my boss is sending an email he sends the email to, eg@example.com.au; and then he will attach our contact group sales@example.com.au
when the email is sent the outgoing email says its going to eg@example.com.au and sales@example.com.au, but when the email has sent and the recipient has gotten the email,
it says its send to eg@example.com.au and staffmember1@example.com.au and staffmember2@example.com.au
and it lists off all staff members emails,

the recipient starts to wonder why my boss is sending his email to all these random names! when in fact we are just the rest of the sales team being kept in the loop!

is there anyway that when the email is sent it can say it has been sent to the recipient and the contact groups name 'sales'

or will it always have the names of the people in the group showing up???

or is their a different way we can approach this to get the same outcome!

THANKYOU
