Replace values in a columns without affecting the other values in the same column

Hi guys!

Being learning a lot about knime, but I am having a hard time trying to process this step. I have to apply 2 filters in 2 columns in order to find a specific value I have to replace.

STEP:

Filter the “Media” column with “Mobile App” values, and then filter the “Property” column with “YouTube App” values.

Them in the resulting data after those 2 filters are applied, go to the “Media” column and replace the "Mobile App” values for “Mobile App Video”.

So easy to process in excel, but knime is killing me. I have tried some nodes that result in affecting the other values that are NOT supposed to be affected in that “Media” column. In these other values that are not supposed to be affected, knime transform then into the red missing value icon, but I need them to remain the same as they were before applying the rule to the “Mobile App/YouTube App” values.

Any suggestion about how to do it?

Just in case for reference, this is the file I am using.
