Hello, I worked with the new function "External Tools" / "Tabluar Editor" to create calculation groups within my model - following a blog post of SQL BI . com . Afterwards I have in EACH table containing DAX measures a hidden display folder called "Format String Measures", which I cannot control (neither from PBI desktop nor from Tabluar Editor). The real problem is a side effect, which is, that I'm loosing the control over the measure formatting in PBI Desktop (Menu "Measure tools" / "Format" field is greyed out). So what did I do wrong? How can I again format my measures in PBI Desktop?
