Contacts, All Fields. Email Fields, Email Address Type WRONG type

Got a strange problem happening.  Add a new contact, enter the contacts external email address save and close.  Check on the contacts email address type and it's listed as SMPT as it should be.  Let it sit for a few minutes and the email type is automatically changing to EX. 

Trying to figure out what is causing this issue and then how does edit the Email Address Type.
