When setting up a calculation item to format a decimal number to percentage all date measures in the model is broken and returns the name of the date format instead of the date itself.

Steps to reproduce the behavior:

1. Go to tabular editor and create a new calculation group and item.
2. Expression = SELECTEDMEASURE ()
3. Format string Expression = "0.00000%"
4. Save the new items to the Power BI file
5. Add the calculation item as a filter to the visual where the decimal is set
6. Activate the calculation item

Expected behavior
The decimal measure should convert from decimal number to percentage format when the calculation item is active. No other changes to behavior expected

Observed behavior
When saving the calculation group and item created in TE the returned values in date measures are broken.

Calculation group and item created, saved to power bi desktop

Percentage formatting working properly, date measures returning "General Da e"

The selected date format for the dates

Changing the date format for the top measure

New result of top measure after refreshing

Application specifics

• Tabular Editor version: 2.12.4 (also tested on 2.13.1)
• Semantic Engine used: Power BI Desktop October 2020 (also tested on November 2020)
• Model Compatibility Level: 1500?

Additional context
The date measures are always broken when saving the calculation group and item to the power bi model. The date measures go back to normal behavior if I delete the calculation item.
