Count and Countrows returning the wrong figure

Hi.

I have a table that contains ~2900 rows with columns. You can see it in the screenshot below.

I am trying to count the orders (each order has a row in this table) and create visualizations based on the figures.

The problem is that the formulas return strange values:

Measure = countrows('Orders') returns 50

Measure = count('Orders'['Count']) returns 50 (after creating the column Count=1)

Measure = calculate(countrows('Initial Orders'),all('initial orders'))  returns the right number, but then if I add Axis (categories of products) I get the same figure for each value.

Please help me figure this out.

Thanks.
