SUMMARY

The items/links presented under "Frequently Used" on the initial page of the system settings can become unusable.

STEPS TO REPRODUCE
1. Open system settings
2. Notice the "Frequently Used" section with items like "Global Theme" or "Audio"
3. Click on one of the items for example "Audio"
4. Now the audio page is loaded
5. Click on the "Home" button on the top left (near the search bar) so you get back to the previous screen where you can see the "Frequently Used" items.
5. Click the SAME item again, in this example "Audio"
6. Notice that nothing happens. Other items still work fine. 

OBSERVED RESULT

The previously used item becomes unusable.

EXPECTED RESULT

I can use the same item multiple times.
