Incorrect Aggregation for Attributes/Alternate Rollup

Hi Guys,

We are having an issue with combining alternate rollups and attributes:

Alternate Rollup: 

There are 4 children - two aggregate positively (+) and two aggregate negatively (+). 

The shared children are not lowest level and are not marked with attributes (only their children) 

Attribute: 

Basic attribute dimension. All aggregations are set to (+).

Issue:

By themselves, they work without any issue.

That is if we start a SV pull and do the Alternate rollup, it works fine. However, as soon as we introduce the Attribute, the data doesn't make any sense.

What we've found in documentation is that Attributes cannot aggregate negatively. I am wondering if this has something to do with it since the data seems to be ignoring the children marked with (-) aggregations.
