StringStoresCompatibilityLevel set to 1100 but still receiving 4GB error

SSAS and SSRS
2

Additional note: The read-only CurrentStringStoresCompatibilityLevel property of the offending dimension continues to read 1050 although the editable StringStoresCompatibilityLevel property of the dimension is clearly set to 1100. How does this read-only property get updated through a GUI, and how does one get these two properties in sync?
