Correcting incorrect titles after scrape

Hi team. Unsure if this is the correct sub-forum to ask this question, but I'll start here.

I have a number of instances in my library where the title selected and stored for a TV show or a movie (as determined from a look-up of the file name) isn't correct. How do I correct the title stored and then displayed for each incorrect entry? I'd hoped there would be the option to change properties, including the title, in the side bar - but no.

Appreciate any advice.
