Problems with Mixed Chart and FIRSTDATE

[Syndicate_Admin]

Good morning

I have a problem with the following chart:

The chart shows a ratio in the columns and the cumulative figure of the same ratio in the line. The problem arises in the value to the left of OCT that captures the value of the cumulative ratio in a space called (blank). The calendar includes dates from October 1st to June 30th, so there is no date before October 1st.

The outline of the measures is as follows:

I can't see what the problem is. If anyone can help me I would be very grateful.

@Syndicate_Admin , You can use the additional date conditions I have used, in your visual

Cumm Sales =
Var _max =maxX(allselected('Sales'), sales[date])
return
if(=max('Date'[date])<= _max, CALCULATE(SUM(Sales[Sales Amount]),filter(all('Date'),'Date'[date] <=max('Date'[date]))), blank())

Cumm Sales =
Var _max =maxX(allselected('Sales'), sales[date])
return
if(=max('Date'[date])<= _max, CALCULATE(SUM(Sales[Sales Amount]),filter(allselected('Date'),'Date'[date] <=max('Date'[date]))), blank())
