When you've clicked on the show and its showing you all the seasons/episodes you have, click on the settings (three dots) and select "Identify"
It'll bring up a menu where you can input the name of the show, or its iMDb code, or a few other identifiers and it'll show the matches it can find. From there you can select the correct show and it'll populate the metadata accordingly
