Loading and saving a session via the API does not appear to carry session over

We have three 'jobs', the first runs our regression tests and saves/archives 
the ZAP session. The second loads this session, runs the spider, and then saves 
the session. The third loads the session and runs the active scanner. The 
session saved in the second job does not appear to contain the data from the 
original session.

What is the expected output? What do you see instead?
I would expect loading and subsequently saving a session to result in a 
combined saved session of the original session plus any session data since 
loading. Instead, it would appear that saving the session only includes new 
data.

What version of the product are you using? On what operating system?

Please provide any additional information below.
For now I will use two jobs, the second will perform both the spider and scan. 
The saved session from this will still be of limited use, but will at least 
perform a complete scan.
