If your table looks like this

I don't know why it didn't work on your side

Since I cannot reporduce your issue, I hope someone can help you.

Have a nice day!

U need to create 2 measures using this colums and use it in visual.

In your case it will be
Measure 1 = SUM(Column 1)

Measure 2 = SUM(Column 2)

And U need to use "clustered column chart" not stacked. ;)
