Customized Column // Transform product names into categories

Hi 

I kindly ask for support regarding the below problem in Power BI. 

I have a column which lists the products sold in a specific project in one row like displayed below (Products combined). I would like to create another customized column which checks the products combined column and returns values based on the following: 

- If products combined column is empty, return empty

- If products combined column contains exactly "Product A,Product B", return Product A including B

- If products combined column contains at least two of the following words/products (Product A, Product B, Product C, Product D), return Solution Project

- Otherwise return value of Products combined column. 

I have tried to use the formula further down below, but apparently there is a mistake in the third IF statement and the result is not displayed correctly (see below in red).  Would be great if you could advise what the mistake is here? If there is an easier way to achieve the expected result, please let me know. Thank you!

IF(
    ISBLANK('Dashboard'[ProductsCombined]),
    BLANK(),
    IF(
        'Dashboard'[ProductsCombined] = "Product A,Product B",
        "Product A including Product B",
        IF(
            CALCULATE(
                COUNTROWS(
                    FILTER(
                        VALUES('Dashboard'[ProductsCombined]),
                        COUNTROWS(
                            INTERSECT(
                                VALUES('Dashboard'[ProductsCombined]),
                                {"Product A", "Product B", "Product C", "Product D", "Product E", "Product F", "Product G"}
                            )
                        )
                    )
                )
            ) >= 2,
            "Solution Project",
            'Dashboard'[ProductsCombined]
        )
    )
)

Thanks in advance!
