“pseudo-loc” what is most appropriate subcategory to file them

That's not a hack. It has to do with an update that's being worked on. https://news.xbox.com/en-us/2018/01/29/whats-learn-pseudo-loc-preview/

It's called pseudo loc and usually appears if the console is enrolled in a Insider preview and downloaded the latest update. It doesn't affect performance; it just looks weird.

To report the error:

1. Press and hold the Xbox button and select Report a problem.

2. Select Report New Issue.

3. Choose the most appropriate category and subcategory.

4. Select your preferred method to complete your report

Hello,

Please submit a report about this.

As per the recent Insider update release notes (for example, Alpha):

Various updates to properly reflect local languages across the console.

Note: Users participating in the Preview may see “odd” text across the console, for more information go here.

If you encounter any kind of pseudo-loc while using the console, just be sure to use the “Report a problem” feature to submit the issue directly on the console. When submitting the issue, be sure to include in your description of exactly where you are encountering the non-localized text.

Hope this helps.
