Access Form - New ID incorrect when trying to enter a new record

Hi

In my Access tabular form which is  bound to a table called "Parts" when I go to enter
a new record where it says "(New)" the ID that is generated is not a new ID but rather an existing older ID.
Why would this happen?

An autonumber ID is not guaranteed to be sequential.  

  The value can be reset:

additionally, the autonumber functionality can break (rarely) and start to generate duplicate numbers.

Hi. Thank you both. I have been using Access since 2005 and never seen this issue, I wonder if the database being in Dropbox may have been the issue

Yes, I would not consider using Dropbox as the storage location for a BE for my database application.
