DAX Count Filtering where a column contains text from another Table's Column

Hello AlB 

I tried with the frutis scenario and it worked but in production it didnt work.

I have the following DAX, the only differece with yours are the ";" which were not recognized and I changed them to ","

CountProducto = 
COUNTROWS (
    FILTER (
        visitas,
        CONTAINSSTRING (visitas[Product],SELECTEDVALUE(UCVisitas_ProductoServicio[Title]))
    )
)

Here is a pic of the info that is not working correctly:

A = The result, as you can see, there es an empty "product".

B = The count of the products (without the filter) where you can see an example of the mixed products (line 3).

C = The products catalog.

What I noticed is the result in production also gives me an empty "Category" (A).

Thank you for your help.
