And like the third time: Keymailer is scanning what is exactly shown on your twitch profile. The video you are linking to is under the category "One Hour One Life", which is the only information keymailer is taking out of your account. Stream, Streamname, Stream Category. If you switch games during a stream, keymailer does not detect that in which case you need to add the tags manually.
The stream shows up under:
Server 6 - Trying for a new civ - Roleplay or DIE - RIP Bananas
Published 8th December 2018
One Hour One Life
You simply need to go to edit tags and add whatever games you have played in the stream.
