question about the type of jobs 22 and 28

Good day!

We have faced a strange issue during automation script development and would like to ask for your assitance. We are trying to collect the statistic data for job types 22 and 28. When we gather statistic using bpdbjobs.exe and bpimagelist.exe we get multiple jobs of type 28 with the same ID but different snapshot ID. At the same time, OPScenter shows only one job of this type. Given all the above, I have a couple of questions and hope you can help me with the answers:

1. Could you please give us more details on how this job type is being produced and why we see this inconsitancy between cli commands and OPScenter?

2. How are these job types are connected? 

Thanks!

Max.
