Problem with bar graph (2 dimensions, 2 formulas)

[#1]

Hi everyone

I have the following problem:

I created a bar graph with 2 dimensions and 2 formulas in order to compare the orders from this year and the previous year in quarters. Now the values from the 2 formulas do not have a separate bar anymore. (See pictures) Does anydody know how to put the results of both formulas (current year and last year) into separate bars?

Thank you for your help!
