Sources of variation does not display numerical maturity with more than one phase (Q941)

Summary: 

For the sources of variation plot of a batch level model (BLM) covering more than one phase, the x-axis displays $MaturityID as an index. 

When the BLM is built on a batch evolution model (BEM) with only one phase, the scale is numerical, VarID($MaturityID).

Workaround: 

Create a batch evolution model for each phase and create individual batch level models.
