Symptom:
There are some inconsistencies in archived configurations, when you compare a raw and processed configurations. 

Raw and processed configuration for same archive should be same

for eg 
I have two versions archived yesterday and today. 
If i compare today's running config with Previous (yesterday), then i see some of the config missing between raw and processed

screenshots attached.

However, if I just open previous running config and compare both processed and raw, it shows all information same.

Conditions:
Comparing previous running/startup configurations with current one
