How reference row context in addcolumn

Thank you for all help! I've managed to find the solution.

ADDCOLUMNS(
   values(Table[Division]),
   "No Cases", CALCULATE(countrows(Table)),
   "No Predictions", CALCULATE(COUNTROWS(Table), Table[Division Prediction]=earlier([Division]), All(Table[Division]))
)

I have used the first column in AddColumns as the table I intend to loop through, which is Division.

Then use Calculate to do a context transition, bringing Table[Division] the row context into the filter context. Hence, "No Cases" will have the correct figure.

Then use Earlier to reference the filter context from outside of Calculate, to use it on Table[Division Prediction]. Remove the filter on Table[Division]
