How to see all versions between two delivery in Rational Team Concert

How to see all versions between two delivery in Rational Team Concert

I did changes and delivered the changes of a file ( Myfile.txt ) with comment "Delivery 1" and that time the Version ID of the file is say 2.
I did the change of the same file , Save it and Checkin with "No Comment" and From History of the File I see Version 3 is Created .
Again I did the change of the same file , Save it and Checkin with "No Comment" and From History of the File I see Version 4 is Created BUT I do not see the Version 3.

I do change again on the same file , Save and Checkin with "No Comment" and From History of the File I see Version 5 is Created BUT I do not see the Version 3.& 4.

Now I deliver the Changes with Comment "Delivery 2 " -- It shows the version of the file as 5

So between "Delivery 2 " and " Delivery 1" -- version 2, 3 and 4 has gone . How I can see version 3 or 4 .

NOTE :: I can not Check in with New Change Set , It indicate the below message
--------- Checking-in changes to new change set
Cannot check-in Myfile.txt because it is already being changed in another active change set.

Instead of picking a specific change set, try allowing the check-in to pick the correct change set.

Can some one help me on this . i,e how to see intermediate versions between two delivery

Thanks
