Hi Robyn,
You are most likely to get answers from the forum if you post an actual example. We are long term users of the tool and would not agree there are a lot of flaws, however the tool is extremely flexible and there are lots of nuances you need to be aware of in order to interpret the data correctly.
Can you screenshot the reports you are trying to understand and I am sure the community can help you!
Cheers
Kristi
