I feel like this is an bug but I have no clue how to resolve this... Can someone say what is going on as when I update it to a new link it seems to work fine but when I update it to null it suddenly gets an different value from when i've updated it some time ago
(In the request headers it sets youtube to null so I have no clue where that youtube video is coming from)
TL;DR
Developers experiencing issue where updating a value to null causes it to revert to original value. Request header shows null value, but a different value is displayed. Potential bug recognized but unsure how to fix.
