it is possible that the authors of the guides have chosen other criterias when selecting the language tag when creating the guide.
That tag will be chosen right at the beginning and you can only choose one of the language tags.

You can select a 2nd language next to your native (primary) language and then they will automatically search for both.

For more information or clarification about bugs you have to wait for another answer.

That's not the reason, in the English Steam client, if you click on the "BROWSE BY" option, the filtered list comes with an "English" tag, but in the Simplified Chinese Steam client However, this tag does not appear in the Simplified Chinese Steam client (I have set the primary and secondary languages).

There is a temporary solution to this bug, which is to check any type and then uncheck it when no guide is filtered, and it will be displayed normally.
