Show active taxonomy term as title of product category view
Edit your Contextual filter and you'll see the option to override the title in the section for when the filter argument is present or a default is provided. 

You can use tokens from the Replacement patterns section to construct the title text. 

Your "menu" is likely also coming from the Contextual filter, set to the "Summary" option.

Another way is to add the title in the Views Header, you can see how it's implemented in the "Taxonomy term" Views.
