Rollup not working in CDS version?

[simon9west]

Describe the bug
in the CDS version (1.0.56.0) the Rollup functions of Sum, Average, Min and Max produce a Zero result regardless of data. In the latest Dynmaics version (1.0.61.1) The Rollup function works fine. Sadly I'm using a Powerapps environment so cannot use this working version.

To Reproduce
Steps to reproduce the behavior:
test on PowerApps and Dynamics environments

Expected behavior
Can you confirm if there are any changes between these two versions and if so, release a new CDS version please?
