MDM - Returning Doubled SQs when Using D2-Math Rule for Multiple Usage Groups across Same Period

If you attempt to bill a rate that leverages the MDM rate code-device config mapping, and separate usage groups are found for a single period, if you use the D2-Math rule to calculate something like max KW, then scalar SQs are included in multiple usage periods leading to a bill for double the consumption.

To re-create:
1. Configure Usage Subscription Type to derive usage group based on Rate-Device Configuration Extendable Lookup
2. Configure a Non-AMI usage group with D2-GetScalar usage rule (to pull KWH) and D2-Math usage rule (to calc. max KW from interval)
3. Configure an AMI usage group with Daily Scalar usage rule (to pull KWH) and D2-Math usage rule (to calc. max KW from interval)
4. Setup the Rate Extendable Lookup as follows:
Rate 1 + Non-AMI DC Type = Non-AMI Usage Group
Rate 1 + AMI DC Type = AMI Usage Group
5. Setup 2 Service Points with following meter installations

Non-AMI Device

AMI Device

6. Create a Usage Subscription with "Rate 1" to include SP1 and SP2
7. Ensure all reads are entered for UT dates
8. Create a UT

Observed Behavior: 2 Usage Periods are generated but KWH from SP1 and SP2, and the calculated max KW are included in both Usage Periods
