Issue/Introduction

STEPS TO REPRODUCE

1. Go to Admin > Studio > Objects
2. Go to the Roadmap object
3. Attributes tab > Create a Time-Varying attribute
   Tested it with Number and Money as data unit 
   Tested it with date constraints and without
4. Go to the MUX > Roadmaps   
5. Add the Time-varying field to the grid view
6. On the View Options, add a period type and Start and End Periods: tested months and years
   Used the Sum of Periods and Grand Totals as Totals
7. On the Grid view, add a value to one of the cells > the total gets updated accordingly.
8. Add a value to another periodic cell, the value is updated
   Notice the previously updated cell value has been zeroed and the total holds the latest cell value
9. Add a value to the total cell 
10. This is zeroed out and all cells are zeroed out too

Expected Results: Per-period metrics behavior to be the same as everywhere else. 
Actual Results: Per-period metrics do not seem to work in the Roadmap object.
